[Also in Division C7] An oxygen electrode for a fuel cell is formed from particles made by stirring a liquid metal to form a foam and introducing the foam into water, whilst stirring the water. The metal may be an indium amalgam, gallium, indiumgallium eutectic or Wood's metal. The particles may be mixed with metal powders or fibres and pressed at 15 tons/cm.<SP>2</SP> in, e.g., a stainless steel container, the outer surface of which is made non-conducting by applying a coating of "Araldite" (Registered Trade Mark) to form an electrode. The electrode may be used with a stainless steel electrode in potassium hydroxide solution. |
