LIQUID ELECTROLYTE FUEL CELL HAVING AN ANODE SUBSTRATE LAYER THICKER THAN THE CATHODE SUBSTRATE LAYER

摘要

A fuel cell (8a) having a matrix (1 1 ) for containing phosphoric acid (or other liquid) electrolyte with an anode catalyst (12) on one side and a cathode catalyst (13) on the other side includes an anode substrate (16a) in contact with the anode catalyst and a cathode substrate (17a) in contact with the cathode catalyst, the anode substrate being thicker than the cathode substrate by a ratio of between 1.75 to 1.0 and 3.0 to 1.0. Non-porous, hydrophobic separator plate assemblies (19) provide fuel flow channels (20) and oxidant flow channels (21 ) as well as demarcating the fuel cells.
