Title:
CATHODE STRUCTURE OF FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2018/214098
Kind Code:
A1
Abstract:
Disclosed is a cathode structure of a fuel cell. The cathode structure comprises a cathode diffusion layer (2), wherein an air permeability adjusting structure is arranged around the cathode diffusion layer (2), and a cathode air permeability of the air permeability adjusting structure gradually varies in the flow direction of a fluid. According to the cathode structure of the fuel cell, by means of arranging the air permeability adjusting structure, with a variable cathode air permeability, around the cathode diffusion layer (2), the difference caused by different temperatures and humidities is subtly compensated for, thus improving the problem of water accumulation or dehydration in the cathode structure of the fuel cell, and effectively improving the water management of the fuel cell.
