  • Fuel cell bipolar plate and fuel cell with improved fluid distribution employing such plates
    Patent number: 7718299
    Abstract: A bipolar plate for a fuel cell including a first through-hole positioned within one of its peripheral edges for circulating a reactive fluid, an anode compartment extending at one of its two main faces, and a cathode compartment extending at the opposite main face. At least one of the compartments is formed completely or partially by a region recessed with respect to the corresponding main face. The recessed region is connected to the through-hole via an intake channel that is recessed within the peripheral edge of the corresponding main face for the reactive fluid to flow into the compartment. A second through-hole located near the first through-hole is provided and is intended for circulating the reactive fluid. The main face opposite the face housing the recessed region comprises a generally non-emergent groove that connects the first and second through-holes.
