The degradation of the air cathode is a key factor affecting the durability of the fuel cells. Air-cathode is one of the most promising designs since it utilizes ambient oxygen as electron acceptor through the passive air diffusion instead of energy-consuming aeration. It uses air as a cathode significantly reducing its weight. Air-cathode is an improved design by compressing the cathode chamber into a hydrophilic thin layer on the surface of the cathode so that the oxygen in air can passively diffuse through the cathodic matrix to the ORR site without aeration.
