Alkaline Fuel Cells (AFC) were developed in 1959 by Francis Thomas Bacon.  Using an alkaline electrolyte such as potassium hydroxide (KOH) in water and cathodes usually made with platinum*.  AFCs are very efficient and offer virtually instant operation without pre-heating, even at sub-zero temperatures.  AFCs have been used by the NASA space program to produce electricity and drinking water. 

An AFC is comprised of a pair of porous electrodes - a positively charged cathode and a negatively charged anode - separated by an alkaline electrolyte (KOH).  Air, containing oxygen, is fed to the cathode gas chamber where it reacts with water to produce four OH-ions and four positive charges.  The OH-ions, attracted by the anode, pass from the cathode through the KOH electrolyte.  Hydrogen, fed to the anode, reacts with the OH-ions to form molecules of water and negative charges.  The electrons are attracted by the positive charge on the cathode and are forced through an external circuit as an electric current.  The reaction produces usable heat and water as a byproduct.

Eco-Friendly*Eco-Friendly Design

Alkaline Fuel Cells are an emissions-free "green" power generation technology. 


Alkaline Fuel Cells (AFC) are among the most efficient types of fuel cells, reaching up to 60% efficiency (up to 87% combined heat and power).  By comparison Proton Exchange Membrane Fuel Cells (PEM) are 40-50% efficient and Solid Oxide Fuel Cells (SOFC) are 55-60%.

*Platinum-Free Catalyst

Reduces capex and opex with no expensive noble metals used in design/production of GenCell Fuel Cells. 

Hydrogen Tanks*Powered by Industrial Grade Hydrogen (99.95%)

Can be powered with industrial grade hydrogen (99.95%) compared to some PEM Fuel Cells that require medical grade hydrogen (99.99%) for operation. 

*Capable of Creating Hydrogen-On-Demand from Anhydrous Ammonia

Recognizing that the limitations of today’s hydrogen infrastructure keep the cost of hydrogen prohibitively expensive as a fuel for primary power, GenCell has developed a revolutionary process that allows you to create hydrogen-on-demand from anhydrous ammonia (NH3) at 10 times the efficiency of other solutions and without any outside electrical power. This breakthrough enables GenCell to provide the first viable green primary power solution for off-grid and poor-grid telecom as well as rural electrification—at a cost less than diesel solutions.

*Cold Climate Performance

Uses a liquid electrolyte (KOH) and has a freezing temperature of -40°C (-40°F), enabling it to rapidly start in both warm and sub-freezing conditions.  This contrasts with PEM and other membrane fuel cells that hydrate their membranes with water and need to operate above 0°C (32°F) or be placed in a heated and insulated enclosure to maintain operation.
