A liquid electrolyte fuel cell (25) includes an electrolyte chamber (26), and two electrodes, one on either side of the electrolyte chamber, which are an anode (10a) and a cathode (10c). Each electrode comprises: a sheet (11) of metal through which are defined a multiplicity of through-holes (14), a first fluid-permeable layer (16) comprising fibrous and/or particulate electrically-conductive material which is bonded to the sheet of metal, in electrical contact with the sheet of metal, and is hydrophobic; and a second fluid-permeable layer (18) comprising electrically-conductive material and catalytic material, which is bonded to the outer surface of the first fluid-permeable layer, and which is at least partly hydrophobic. The cell (25) is structurally asymmetric, as a larger proportion of the area of the sheet in the cathode (10c) is holes than is the case in the anode (10a). |
