Abstract: A continuous process of removing ammonia gas from a gas stream is disclosed. A bed of solid porous material is provided which is wetted with an acid and the ammonia gas is removed by reacting with the acid to form an ammoniated salt. The porous material containing the acid is held at an electrochemical potential sufficient to oxidize the ammoniated salt of the acid to produce nitrogen gas regardless of the content of the gas stream. The porous substrate can be flooded with an insulating layer to permit entry of only the formed salt and barrier to the, for example, reducing gas, thereby improving the efficiency of the system.

Abstract: FUEL CELL STRUCTURE In a stack of electrochemical cells, such as fuel cells, distinct channels behind each electrode for carrying reactant gas are eliminated by using highly porous gas distribution layers, such as porous electrode substrate material. This gas distribution layer must be sufficiently thick and have enough pores sufficiently large to permit a substantially free flow of reactant gas therethrough both perpendicular to and parallel to the catalyst layer.
