Abstract
A gas fueled fuel cell including spaced anode and cathode electrode parts defining anode and cathode gas chambers, means to conduct anode and cathode fuel gases into the chambers and a unit between the parts and separating the chambers. Said unit includes spaced rigid gas and liquid permeable anode and cathode laminates with outer surfaces disposed toward the anode and cathode chambers. Said outer surfaces have catalytic material deposited thereon and establish chemically reactive interfaces between the laminates and their related chambers. The outer surfaces are covered with gas permeable hydrophobic barriers. The cell next includes spacer means between the laminates including a layer of gas and liquid permeable dielectric material. Finally, the cell includes an ion permeable electrolyte compound between spaced opposing inner surfaces of the gas and liquid permeable laminates. The electrolyte is an acid-salt compound which is solid at temperatures below the operating temperatures of the cell and becomes liquid and has increased ion permeability when the cell is heated to operating temperature by chemical reaction therein.
