A fuel cell comprises an electrolyte chamber (208), and comprising two electrodes (10a, 10b), one on either side of the electrolyte chamber (208). Each electrode comprises a fluid-permeable layer of electrically-conductive material, and also a catalytic material. The fluid-permeable layer comprises a permeable polymer matrix comprising polymer particles (120) bonded together at points of contact (125), and particulate electrically-conductive material such as carbon nanotubes (122) for electrical conductivity. |
