Breakthrough in fuel cell research

The Dalian Institute of Chemicals' 5kW-level methanol autothermal reforming hydrogen source system and fuel cells have recently been successfully tested. The integrated reforming hydrogen source system and reformed gas fuel cell technology mark the importance of an autogenous reforming hydrogen source system in methanol. A breakthrough has been made in the development of gas-solid fuel cells.
Dalian Chemicals has a solid foundation in the hydrogen-air fuel cell technology. In order to commercialize the fuel cell as quickly as possible, it also serves as one of the main contents of the “High-power fuel cell engine and its hydrogen source technology” in the major project of Knowledge Innovation Engineering of the Chinese Academy of Sciences. After two months of preparation and commissioning, the Institute’s scientists and technicians succeeded once and for all. During the six-hour joint test, the working conditions of the hydrogen source system and the fuel cell system were normally stable, the CO concentration in the methanol reformed gas was about 3×10-5, the hydrogen content reached 53%, and the fuel cell output power was It is always maintained between 5 and 5.2 kW. The joint test results not only proved that the fuel cell's anti-CO capability is very good, but also uses the fuel cell tail gas as the fuel gas for the hydrogen production system to realize the energy balance and optimal utilization of the whole system.
The problem of hydrogen source has been one of the technical bottlenecks that hinder the commercialization of mobile power sources such as on-board fuel cells. Compared with the hydrogen supply method of pure hydrogen, on-site preparation of fuel cells by means of reforming hydrocarbons such as natural gas, methanol, and gasoline, has the advantages of high energy density, high energy conversion rate, easy transport of liquid fuel, and supplementation. Features such as storage also have advantages in economy and safety. The success of the joint test of 5kW mobile methanol autothermal reforming hydrogen production prototype and fuel cell has accumulated valuable experience for the integration of the 75kW methanol reforming hydrogen source fuel cell system.
