Abstract
The fuel cell (100) includes an oxidant flow plate (212), an adjacent cathode substrate layer (216) having a cathode catalyst (222), a matrix (224) for retaining a liquid electrolyte (230), wherein the matrix (224) is secured adjacent and between the cathode catalyst (222) and an anode catalyst (232). A first anode substrate (102) is secured adjacent the anode catalyst (232), and at least a second duplicate anode substrate layer (108) is secured adjacent the first anode substrate layer (102) for providing greater pore volume for storage of the liquid electrolyte (230) and to limit obstruction of the pore volume of the anode substrates (102, 108). The duplicate anode substrate layer (108) may be partially filled with the liquid electrolyte (230) at the beginning of life of the fuel cell (100).
