The minor portion of a fuel cell electrode projects into a chamber containing fuel gas or oxidant gas such that the gas diffuses rapidly through the porous catalyst coating on the electrode into the major electrode portion which is submerged in liquid electrolyte. Bags 12a, 12c enclosing the minor portions of anode 1 and cathode 2 are supplied with gas, the gas-tight bags being bonded at 13 to the electrodes, or the electrodes 102a, 102c are immersed in electrolyte in a central compartment 103 and project into lateral compartments 104a, 104c supplied with fuel gas or oxidant gas, resin seals 106 being provided on the electrodes. The electrodes are planar or curved, Figs. 10-12 (not shown). The anode is a nickel grid covered with palladized active carbon and the cathode is a silver or nickel grid covered with silvered active carbon, while the electrolyte is a potassium solution. The fuel gas is hydrogen and the oxidant gas is air.
