Estimating the term…
A fuel cell structure with a porous metal plate includes a membrane electrode assembly (MEA), a first porous metal plate, a metal plate, and a pair of end plates. The first porous metal plate and the metal plate are disposed on opposite outer surfaces of two gas diffusion layers (GDLs) of the MEA, respectively, and have fuel channels contacting with the GDLs. The end plates are arranged on outer surfaces of the first porous metal plate and of the metal plate, respectively, to close cooling-liquid flow channels of the first porous metal plate and of the metal plate. A pressure difference between fuel and cooling liquid within the fuel cell structure pushes the cooling liquid flowing through the cooling-liquid flow channels of the first porous metal plate to seep into the fuel channels spontaneously and hence humidify the fuel automatically, thereby maintaining the reaction efficiency of the fuel cell structure.
A fuel cell structure with a porous metal plate, comprising:
A porous metal plate structure for use in a fuel cell, the porous metal plate structure comprising a metal plate body, the metal plate body having one surface formed with at least one fuel channel and the other surface formed with at least one cooling-liquid flow channel.
