A gas electrode for a fuel cell consists of a current conducting element placed between an electrolytic soln. and a gas compartment. There is a catalytic layer (I) on at least one face of the conducting element. On the external surface of the catalytic layer facing the gas compartment there is a layer (II) impermeable to the electrolyte soln. but permeable to gas. (I) and (II) are formed by porous particles of active carbon, bound together by a plastic material which is chemically inert w.r.t. the reaction medium. The pores are coated internally with a material, also chemically inert, which provides hydrophobic properties. The electrode is easy to mfr., has pores of regular, constant dia., and gives improved performance w.r.t. previous electrodes. |
