FIELD: electrical engineering; fuel cells.
SUBSTANCE: proposed fuel cell bipolar plate has plate proper, fluid passage space formed on both sides of plate, and fluid guide screen installed in fluid flow space. Formed on plate are inlet and outlet channels communicating with fluid flow space. Bipolar plate is manufactured by means of special mold and using special treatment process. As a result, flow distribution is more uniform and its resistance to fuel and air flow to fuel-cell fuel electrode and air electrode, respectively, is reduced. In addition, area of reaction with membrane-electrode assembly and diffusion area can be increased.
EFFECT: improved design, facilitated manufacture.
