The terminology \u2018dry-cell\u2019 came into the public domain as a \u2018trade name\u2019 for Brown\u2019s Gas, likely originating from Denny Klein during the explosion of on-board\u00a0electrolyzer<\/dfn>\u00a0experimentation that happened during 2008.<\/p>\n

The originator popularized the term \u2018dry-cell\u2019 to differentiate the \u2018recirculating-electrolyte<\/dfn>\u2018 electrolyzer designs (dry-cell) from the original electrolyzers that did not recirculate the electrolyte (wet-cell).<\/p>\n

The \u2018dry-cell\u2019 is a misnomer. \u00a0Dry-cells do NOT use dry (no liquid) electrolyte. \u00a0In fact, they usually use MORE liquid electrolyte than the original simple design; that they re-named a \u2018wet-cell\u2019.<\/p>\n

A so-called \u2018dry-cell\u2019 is simply a full flooded wet-cell with an additional reservoir for electrolyte and a means to circulate the electrolyte fluids, (liquid and gas mixture) between the electrolyzer and the reservoir.<\/p>\n

I think they were named \u2018dry\u2019 because they, theoretically, could have a smaller portion of the liquid electrolyte in the cell-pack at any given time.\u00a0<\/em>\u00a0This is actually not true in a lot of cases<\/strong>.<\/p>\n

The dry-cell\u2019s fluid reservoir is usually mounted higher than the cell-pack and is connected to the cell-pack so that the natrual \u2018rising\u2019 action of convection (heated liquid electrolyte) and gas bubbles will \u2018pump\u2019 the electrolyte\/gas mixture up out of the electrolyzer, allowing fresh electrolyte to flow into the bottom of the electrolyzer.<\/p>\n

A \u2018dry-cell\u2019 is simply an \u2018electrolyte circulating electrolyzer system\u2019. \u00a0The electrolyzer portion of the system can be, and usually is,\u00a0EXACTLY the same design as the original<\/em>\u00a0(now \u2018re-named\u2019 wet-cell).<\/p>\n

Typically the dry-cell\u2019s reservoir is used to separate the\u00a0BG<\/dfn><\/a>\u00a0(aka HHO) and electrolyte fluid, allowing the BG to exit from the system and the de-gassed electrolyte to re-enter the bottom of the electrolyzer.<\/p>\n

Dry-cells can be designed using\u00a0parallel-plate or series-plate<\/strong>\u00a0configurations; exactly the same as the original wet-cells. \u00a0I say again\u2026 Nearly ANY electrolyzer can be converted to be a \u2018dry-cell\u2019 just by adding a reservoir tank and recirculation hoses. \u00a0BUT just because it\u2019s a dry-cell DOESN\u2019T make it more efficient, most often just the opposite is true.<\/p>\n

Some advantages of the dry-cell concept include:<\/p>\n

1. An increased ability to control the temperature of the electrolyte. \u00a0For any given electrolyzer design, frequency, pulse (width and shape), electrolyte and electrolyte concentration there will be an ideal or optimum temperature.<\/p>\n

Sometimes the BG production increase can be dramatic if the optimum temperature is maintained; so all electrolyzers should have temperature control, allowing heating or cooling as needed.
\nOur\u00a0HyZor<\/dfn>\u00a0is an \u2018integrated dry cell\u2019 because the \u2018extra reservoir\u2019 is built into the body.<\/em><\/p>\n

2. The ability to mount the reservoir tank separately from the electrolyzer, supposedly allowing easier filling with water and easier placing of components within the vehicle. \u00a0Easier filling may not be actually true, depending on the electrolyzer and the location of the reservoir tank.
\nOur HyZor is\u00a0designed<\/strong>\u00a0to be filled remotely and includes electronics to monitor fluid level<\/em>.<\/p>\n

3. The ability to remove bubbles from the electrolyzer faster than natural convection, particularly if using a pump. \u00a0Using a pump to increase \u2018dry-cell\u2019 efficiency is highly recommended<\/em>.<\/p>\n

4. The ability to \u2018treat\u2019 all the electrolyte, filtering out solids and\/or changing the electrolyte density easily and quickly. \u00a0In some cases, this can be a practical advantage<\/em>.<\/p>\n

The usual concept is to have the BG, generated in the electrolyzer, lift itself and some electrolyte out of the electrolyzer using bubble-assisted convection or pump assisted convection. The upper tank then allows the BG to separate from the electrolyte fluid (at it\u2019s own convenience) and the, now clear, electrolyte then falls back (through a separate tube) to the bottom of the electrolyzer, to continue the process.<\/p>\n

The dry-cell may also cause more ExW to form, as cations and anions can be \u2018pushed\u2019 out of the electrolyzer with the BG\u00a0before<\/em>\u00a0they have a chance to complete their chemical dance.<\/p>\n

My advise would be to provide a pump for positive circulation of the electrolyte. Maximizing the advantages above (particularly as I\u2019m finding that temperature control may be a major factor in finding the peak performance point) and minimizing the inevitable \u2018surging\u2019 that happens with passive bubble-assisted circulation (surging causes portions of plate surfaces to become inactive).<\/p>\n

Also, it is VITAL to remove bubbles from the active electrode surfaces ASAP to raise electrolyzer efficiency. \u00a0Every bubble that is stuck to a surface is preventing that portion of the surface from participating in the\u00a0electrolysis<\/dfn>\u00a0process. \u00a0Less surface area causes a higher\u00a0amperage<\/dfn>\u00a0density and higher cell voltages; both of which reduce wattage efficiency. \u00a0A pump forces the fluids, including the bubbles formed on the plates, to be ejected from the cells; allowing the electrolysis process to be more efficient.<\/p>\n

Also, most dry-cells are miss-designed for maximum efficiency, because they enter and exit the fluid through the side-plates. \u00a0This causes flow, surging and \u2018shorting\u2019 issues.<\/p>\n

Fluid for each cell should enter from directly below each cell and exit directly above each cell, using manifolds (like these people did<\/a>). \u00a0If fluids from one cell can access another cell, electricity can \u2018short\u2019 between the cells and cause lower efficiency.<\/p>\n

Our HyZor, as currently designed, is a compact,\u00a0integrated hybrid wet\/dry electrolyzer\u00a0wherein the bulk of the electrolyte is separate from the (dual) electrolyzers and electrolyte CAN circulate in and out of the cells.\u00a0<\/em><\/p>\n

I have not yet seen a dry-cell that can match or exceed the efficiencies of our current HyZor design, which has achieved\u00a020+ MMW.<\/em><\/strong><\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product-resource-group":[99],"restricted-resource-tag":[],"class_list":["post-851","product-resource","type-product-resource","status-publish","hentry","product-resource-group-er50-resources"],"acf":[],"_links":{"self":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource\/851","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource"}],"about":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/types\/product-resource"}],"wp:attachment":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/media?parent=851"}],"wp:term":[{"taxonomy":"product-resource-group","embeddable":true,"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource-group?post=851"},{"taxonomy":"restricted-resource-tag","embeddable":true,"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/restricted-resource-tag?post=851"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
