The car "Schluckspecht" completed a successful test drive on Nogaro Circuit, powered by a DEFC stack giving an output voltage of 20 to 45 V (depending on load). [4] Various prototypes of Direct Ethanol Fuel Cell Stack mobile phone chargers have been built [5] featuring voltages from 2V to 7V and powers from 800 mW to 2W [6] were built and tested.
Electro-chemical reaction Diagram of PEM MEA. A membrane electrode assembly (MEA) is an assembled stack of proton-exchange membranes (PEM) or alkali anion exchange membrane (AAEM), catalyst and flat plate electrode used in fuel cells and electrolyzers. [1] [2]
If the fuel is a light hydrocarbon, for example, methane, another function of the anode is to act as a catalyst for steam reforming the fuel into hydrogen. This provides another operational benefit to the fuel cell stack because the reforming reaction is endothermic, which cools the stack internally.
Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]

SOEC 60 cell stack. A solid oxide electrolyzer cell (SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water (and/or carbon dioxide) [1] by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas [2] (and/or carbon monoxide) and oxygen.
Stationary fuel cell applications Stationary fuel cell applications (or stationary fuel cell power systems) are stationary (not moving) fuel cell applications Steady state Steady state is a more general situation than dynamic equilibrium. If a system is in steady state, then the recently observed behavior of the system will continue into the ...
