Abstract
A cathode structure of a fuel cell is disclosed. The cathode structure comprises a cathode diffusion layer, wherein an air permeability adjusting structure is arranged around the cathode diffusion layer, and the cathode air permeability of the air permeability adjusting structure gradually varies in the flow direction of fluid. According to the cathode structure of a fuel cell, by means of arranging the air permeability adjusting structure, with variable cathode air permeability around the cathode diffusion layer, the difference caused by different temperatures and humidity is subtly compensated for, thus improving the problem of water accumulation or dehydration in a cathode structure of a fuel cell, and effectively improving the water management of the fuel cell.
