The invention provides a unified resolvent for the humidification of reaction gas, membrane hydration, removal of generating water and cell cooling by the processing of the diffusion layers.

Description

technical field [0001] The invention relates to a polymer fuel cell, specifically a single-layer bipolar plate fuel cell with the functions of gas humidification, membrane hydration, water removal and cell cooling. Background technique [0002] A fuel cell is an energy reduction device that converts chemical energy stored in fuel and oxidant isothermally into electrical energy according to the electrochemical principle. The essence of the electrochemical reaction is the combustion reaction of hydrogen. It differs from ordinary batteries in that the positive and negative electrodes of fuel cells do not contain active materials, but only play a role in catalytic conversion. The required fuel (hydrogen or produced by reforming fossil fuels such as methane, natural gas, coal gas, methanol, ethanol, gasoline or bioenergy) and oxygen (or air) are continuously input from the outside, so the fuel cell is a veritable chemical A device that converts electrical energy. There are many...
