Product Overview
DiffuCarb® E202c and DiffuCarb® E222c are platinum-based carbon paper electrodes for HT-PEMFC applications. They are suitable for high-temperature PEM fuel cell research, single-cell testing, membrane electrode assembly preparation, backup power systems, and hydrogen fuel cell vehicle validation.
Both electrodes use highly conductive carbon paper as the substrate and a PTFE binder system to balance electrical conductivity, gas permeability, hydrophobicity, and high-temperature structural stability. E202c uses a platinum/high-surface-area carbon supported catalyst system, emphasizing durability and platinum utilization. E222c uses a high-surface-area platinum black system, emphasizing abundant active sites and fast reaction response.
DiffuCarb® E202c
Pt/HSC carbon paper electrode. Recommended for stable high-temperature operation, long-term continuous use, and HT-PEMFC systems requiring strong structural durability.
DiffuCarb® E222c
High-surface-area Pt Black carbon paper electrode. Recommended for high reaction activity, fast dynamic response, and high-performance fuel cell output.
DiffuCarb® E202c Pt/HSC Carbon Paper Electrode (22BB)
DiffuCarb® E202c is a high-performance electrode material designed for high-temperature PEM fuel cells. It uses highly dispersed platinum catalyst supported on high-surface-area carbon, bonded into conductive carbon paper with PTFE. This structure is suitable for harsh operating environments while balancing catalytic efficiency, structural stability, and gas diffusion capability.
DiffuCarb® E222c High-Surface-Area Pt Black Carbon Paper Electrode (22BB)
DiffuCarb® E222c uses highly active platinum black as the core catalyst, providing a large reaction surface area and improving reaction rates for hydrogen oxidation and oxygen reduction. Combined with porous carbon paper and a PTFE binder system, it balances electrical conductivity, gas permeability, and high-temperature stability.
