NJDL Fuel Cell Material Technology Co., Ltd. has developed a nano-porous carbon film.
Nano-porous carbon film is a new type of carbon material. Its microstructure is like a sponge, and carbon accounts for more than 95% of the basic components. Most of the porous carbon materials on the market can only be obtained in powder form, which greatly limits the scope of application and affects the use effect.
In the past decade, many bulk (or continuum) nanoporous carbon materials have been developed, but these materials have low mechanical strength, low electrical conductivity, low porosity, nano-pore non-continuity, and pore orientation Uncontrollable and many other issues.
However, nanoporous carbon membranes developed by momentum materials have certain mechanical strength and toughness, and are easy to be processed into electrodes. They can be used as catalyst carriers or microporous layers for hydrogen fuel cells. The nanoporous carbon film-based catalyst layer surpassed the traditional carbon black-based catalyst layer in key indicators such as performance and life.
More importantly, the catalyst layer will greatly simplify the production process of hydrogen fuel cell membrane electrodes, and realize the micro-controllable distribution of core reaction materials such as catalysts, carbon scaffolds, and proton conductors, so as to achieve the operability of battery production. Momentum person in charge of human resources Xiao An said that the use of porous carbon membrane can effectively improve battery performance and life. Experimental data show that the membrane electrode life can be more than doubled after using nanoporous carbon membrane.
Due to its controllable pore channels, nanoporous carbon membranes can also be used as filter membranes in ultrafiltration and nanofiltration equipment. In addition, the nanoporous carbon membrane has electrical conductivity that can also achieve some functions that ordinary filter membranes cannot achieve, such as electrical sterilization and virus killing. In the future, nano-porous carbon membranes will be widely used in industrial and civil fields such as organic synthesis, chemical industry, biochemistry, electronic cigarettes, air purifiers, and aldehyde removal products.
