phosphoric acid fuel cell uses a liquid phosphoric acid
electrolyte in a silicone carbide matrix to carry hydrogen
ions from the anode to the cathode. The operating temperature
range is 100-200 °C.
The fuel cells are designed for ease of use and many years
of service. Gas diffusion electrodes (ordered separately)
are held in place between graphite cellblocks. Flow fields
machined into the blocks allow for the flow of reactants
and provide excellent electrical contact to the Membrane
Electrode Assembly electrodes. Current is collected by
connection to copper contact plates; separate voltage
connectors are provided directly in the cellblocks for
maximum accuracy in iR measurement. Each unit includes
resistive heaters and thermocouple wells for accurate
temperature control. The cell is equipped with a reservoir
for the continuous supply of phosphoric acid to electrodes.
Phosphoric acid fuel Cell
Matrix Electrodes Unit: EC-LE-Matrix
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. The manufacturer also provides the matrix assemblies which consist of Pt Catalyst with silicone carbide coating – carrying hydrogen ions from the anode to the cathode.
- Electrode Size: 17 x 17 cm
