The invention discloses a novel fuel
cell based on
graphene thermoelectric management
layers. The novel fuel
cell comprises a flow field plate, a
diffusion layer, an
anode catalytic layer, a
proton exchange membrane, a
cathode catalytic layer, a
diffusion layer and a flow field plate, wherein the
anode catalytic layer and the
cathode catalytic layer both belong to catalytic
layers, the novel fuel
cell is characterized in that the
graphene thermoelectric management
layers are arranged between the
anode catalytic layer and the
diffusion layer and between the
cathode catalytic layer and the
diffusion layer and are prepared by mixing
graphene, an
alcohol solvent and a dispersing agent, and micro-sized concave-convex structures are arranged on the front surface and the back surface of the
proton exchange membrane. The graphene-based thermoelectric management layers have ultrahigh
electron conduction rate and ultrahigh
thermal conduction rate, electrons generated during the electrochemical reaction process of the catalytic layers of the fuel cell and required electrons can be rapidly exported and imported, electrochemical polarization and ohmic polarization are reduced, and output performance is improved; moreover, a large amount of
waste heat generated by a catalyst can be rapidly discharged, and stable electrochemical reaction is maintained; and meanwhile, temperature and
electric field in the catalytic layers also can be balanced, and the service life of the fuel cell is prolonged.
