A liquid-distributing channel (222, 224, 226) having an aperture (232, 234, 236) transports liquid electrolyte to and from a porous cathode (218) in a cation exchange membrane (CEM) fuel cell, the porous cathode (218) being adjacent the channel's aperture. The channel has a width greater than the width of its aperture so as to provide reduced flow resistance of the channel. The aperture (232, 234, 236) is wide enough to allow the liquid electrolyte to pass between the channel (222, 224, 226) and the porous cathode and small enough to inhibit ingress of the porous cathode (218) into the channel (222, 224, 226) due to the porous cathode (218) being compressed against the channel (222, 224, 226), or due to the porous cathode (218) being forced against the channel (222, 224, 226) by flow of the liquid into the channel from the porous cathode (218). |
