The Liquid Electrolyte fuel cell is equipped with a reservoir for the continuous supply of liquid fuel (i.e. electrolyte) to electrodes.  It provides an easy assembly structure to install the electrode and fill the liquid fuel.  Since the fuel (electrolyte) is liquid, the solution is soaked in a matrix so that t it can be contained in the fuel cell.

Flow fields machined in to the graphite plates allow the flow of reactants and provide excellent electrical contact to the matrix.

You can also purchase the matrix assemblies which consist of Pt Catalyst with silicone carbide coating – carrying hydrogen ions from the anode to the cathode.

Liquid Electrolyte Fuel Cell Hardware Includes:

✔ Machined graphite separator plates
✔ Gold plated current collectors
✔ Banana plugs for monitoring voltage
