Abstract

The present disclosure relates to a cooling flow field arrangement for a fuel cell comprising: a plurality of outlet manifolds; a plurality of inlet manifolds, each adapted to receive coolant at a different temperature. The present disclosure adjusts the temperature of the cooling liquid to prevent the formation of hot spots caused by different electrochemical reaction rates caused by temperature inhomogeneity due to the temperature inhomogeneity in the catalyst layer, thereby improving the service life and efficiency of the fuel cell.

Description

technical field [0001] The present disclosure relates to the field of fuel cells, and in particular, to a cooling flow field device and a fuel cell. Background technique [0002] A fuel cell is a chemical device that can directly convert the chemical energy of fuel into electrical energy, also known as an electrochemical generator. Fuel cells use fuel (such as hydrogen) and oxygen as raw materials, and there are no mechanical transmission parts, so there is no pollution and very little harmful gas is emitted. It can be seen that from the perspective of saving energy and protecting the ecological environment, fuel cells are one of the most promising power generation technologies. [0003] The efficient operation of proton exchange membrane fuel cells relies heavily on a cooling system that effectively cools the entire catalyst layer. The uneven temperature in the catalyst layer leads to different electrochemical reaction rates at different locations, which can lead to the f...
