Research on the Performance Enhancement of Porous Carbon in Fuel Cells

With the continuous growth of energy demand and the increasingly serious environmental pollution problems, fuel cells have attracted much attention as a clean and efficient energy conversion technology. Fuel cells achieve zero emission and high-efficiency energy conversion by converting chemical energy into electrical energy, and are one of the important directions for future energy development. As one of the key materials in fuel cells, porous carbon can enhance the performance of fuel cells and has important research value and application prospects.

Porous carbon is a carbon material with high specific surface area and pore volume, which has excellent conductivity, chemical stability, and high temperature resistance. In fuel cells, porous carbon can be used as a carrier material, catalyst support material, and electrode material for various purposes, which can improve the performance and stability of fuel cells. The research on the performance improvement of porous carbon in fuel cells mainly includes the following aspects:

Firstly, porous carbon as a carrier material can increase the loading and dispersion of the catalyst, and enhance the catalytic reaction activity. Porous carbon has a rich pore structure and pore channels, which can provide more active sites and catalytic reaction sites, which is beneficial for the adsorption and reaction activity of catalysts. Meanwhile, the high conductivity of porous carbon also facilitates electron transfer and catalytic reactions, improving the efficiency and stability of fuel cells.

Secondly, porous carbon as a catalyst support material can improve the stability and lifespan of the catalyst. Porous carbon has high chemical stability and high temperature resistance, which can effectively prevent catalyst detachment and aggregation, and extend the service life of the catalyst. Meanwhile, the pore structure and pore channels of porous carbon can effectively reduce the self aggregation and poisoning phenomena of the catalyst, maintaining its activity and selectivity.

Porous carbon as electrode material can improve the electrochemical performance and cycling stability of fuel cells. Porous carbon has high electrical conductivity and conductivity, which can effectively improve the electron transfer rate and response speed of the electrode, reduce the polarization loss and internal resistance of the electrode. Meanwhile, the pore structure and pore channels of porous carbon can also provide more hydrogen storage and mass transfer channels, which is beneficial for gas adsorption and diffusion, and improves the polarization performance and stability of the anode and cathode.

Overall, porous carbon has important application prospects and research value in fuel cells, which can improve the performance and stability of fuel cells and promote the development and application of fuel cell technology. Future research directions include the synthesis and characterization methods of porous carbon, the interaction mechanism between porous carbon and catalysts, and the application and performance optimization of porous carbon in fuel cells. This will provide important technical support and scientific basis for the commercialization and industrial application of fuel cells.
