A fuel cell

Abstract

The application relates to a fuel cell, comprising: a plurality of real battery monomers arranged in stacks, the surface of each real battery monomer is provided with a flow field, the first flow field comprises a plurality of first flow channels; a liquid supply manifold in communication with one end of the first flow field to supply a heat exchange medium to the first flow field; a liquid discharge manifold in communication with the other end of the first flow field to discharge the heat exchange medium in the first flow field; a separation mechanism connected with the liquid supply manifold, used for separating bubbles in the heat exchange medium and feeding the heat exchange medium after the bubbles are separated into the liquid supply manifold; an exhaust manifold connected with the separation mechanism, used for discharging the separated bubbles; a false battery monomer arranged in stacks with the plurality of real battery monomers, the surface of the false battery monomer is provided with a second flow field, one end of the second flow field is in communication with the exhaust manifold and the other end is in communication with the liquid discharge manifold, so as to guide the bubbles in the exhaust manifold to the liquid discharge manifold for discharge. The application can alleviate the local overheating caused by the blockage of the first flow channel on the surface of the real battery monomer, and is also economical and environment-friendly.
