Cell performance of polymer electrolyte fuel cell with urchin-like carbon supports

- CNTs were grown on mesoporous carbon as good catalysts support for PEFC.
- The optimal hot-pressing pressure to form MEA was found with this type of support.
- The optimal CNT growth time is 60 min for the single cell of both DMFC and PEMFC.
- The maximum power densities were improved by 43 and 79% for DMFC and PEMFC.
- Similarly, this catalyst also has notably higher maximum power densities than E-TEK.
