AI Technical Summary
In existing technologies, the porosity of the catalyst layer cannot be effectively adjusted, resulting in insufficient catalyst utilization, conversion rate and lifespan. In particular, the performance is limited under high current density, affecting the performance of fuel cells, electrolyzers, batteries and supercapacitors.
By using low-dispersion porous spherical carbon particles and controlling their particle size and templated pore size, an adjustable 3D porous structure is constructed to ensure precise control of intraparticle porosity and interparticle porosity, thereby optimizing mass transfer.
It improves the catalyst utilization, conversion rate and stability of the catalyst layer, enhances performance at high current densities, and improves the power density of fuel cells and electrolyzers and the capacity retention of batteries.
