  • Publication number: 20180145342
    Abstract: A flow field including graphene foam for a fuel cell. The flow field is made of graphene foam that enhances mass transport and suffers no corrosion under operating conditions of the fuel cell when compared with conventional flow fields. In addition, compressed graphene foam has smaller in-plane pores due to the compression and has more tortuous pathways for flowing reactants, thereby increasing retention time of reactants and accelerating diffusion of reactants into a gas diffusion layer (GDL). Further, large through-plane pores inside the graphene foam transport reactants to entire areas of a catalyst layer, and faster flow velocity compared with the conventional membrane electrode assembly (MEA) is derived from a decreased flow field width due to compression. Therefore, mass transport of reactants and products is enhanced, and performance of the fuel cell is improved at high current density regions.
