Gas fueled fuel cell
An elongate fuel cell structure is described including an anode electrode part at one end defining a longitudinally inwardly opening anode gas chamber, a cathode electrode part at the other end defining a longitudinally inwardly opening cathode gas chamber spaced from and opposing the anode gas chamber. The anode and cathode electrode parts have ports communicating with the chambers and connect with supplies of anode and cathode fuel gases, an intermediate unit between and separating the anode and cathode parts and the anode and cathode gas chambers. The unit includes a pair of longitudinally spaced structurally sound and dimensionally stable porous gas and liquid permeable anode and cathode laminates with flat, longitudinally outwardly disposed outer surfaces disposed toward their related anode and cathode chambers and flat spaced opposing inner surfaces, deposits of catalytic material at the outer surfaces of the anode and cathode laminates establishing chemically reactive interface zones at those surfaces, gas permeable hydrophobic barriers at the outer surfaces of the laminates between the gas chambers and chemical reaction interface zones at the laminates, an ion permeable acid-salt melt electrolyte compound between the laminates and permeating the laminates to the chemical reaction interface zones.
