Abstract[English]
Disclosed herein are aspects of methods, devices and systems of uniform current density in a fuel cell assembly. Asymmetrical bipolar plates provide for even fuel distribution across a membrane electrode assembly anode surface and forced diffusion of coolant across the cathode surface of the membrane electrode assembly and each of which improves current density. Uniform current density across each fuel cell forming a fuel cell stack yields a fuel cell stack having higher current density.[French]
Des aspects de procédés, de dispositifs et de systèmes de densité de courant uniforme dans un ensemble pile à combustible sont divulgués dans l'invention. Des plaques bipolaires asymétriques permettent une distribution uniforme de combustible à travers une surface d'anode d'ensemble électrode à membrane et une diffusion forcée de liquide de refroidissement à travers la surface de cathode de l'ensemble électrode à membrane, chacune améliorant la densité de courant. Une densité de courant uniforme à travers chaque pile à combustible formant un empilement de piles à combustible produit un empilement de piles à combustible ayant une densité de courant plus élevée.
