Fuel Cell

The heart of fuel cells-membrane electrodes Ordered membrane electrode is undoubtedly the main direction of the next generation of membrane electrode preparation technology. While reducing the platinum group element load, the following 5 aspects need to be further considered: 1) Ordered membrane electrode is very sensitive to impurities; 2 ) Broaden the operating range of membrane electrodes through material optimization, characterization, and modeling; 3) Introduce fast proton conductor nanostructures in the catalytic layer; 4) Low-cost mass production process development; 5) In-depth research on membrane electrode proton exchange membranes, electricity The interaction and synergy between the catalyst and the gas diffusion layer.

  Fuel Cell Structure The main components of a fuel cell are: electrodes, electrolyte membrane and current collectors. 1. Electrode The fuel cell electrode is an electrochemical reaction site where the fuel undergoes oxidation reaction and the oxidant undergoes reduction reaction. The key to its performance lies in the performance of the catalyst, the electrode material and the electrode manufacturing process. The electrode can be divided into two parts. One is the anode and the other is the cathode. The thickness is generally 200-500mm. The structure is different from the flat electrode of the ordinary battery. The fuel cell electrode is a porous structure, so it is designed to be porous. The main reason for the structure is that most of the fuel and oxidant used in the fuel cell are gases, and the solubility of the gas in the electrolyte is not high. In order to increase the actual working current density of the fuel cell and reduce the polarization, a porous structure has been d...
