Abstract

The development of a low‐cost and high‐performance fuel cell is a strong social demand. Anion‐exchange membrane fuel cells (AEMFCs) have recently emerged as an alternative technology to conventional fuel cells that use a proton‐exchange membrane as they enable the use of cheaper metals than platinum. An AEMFC exhibiting a maximum power density of 241 mW cm−2 based on a palladium‐based electrocatalyst has been developed. The polybenzimidazole‐wrapped carbon nanotubes were used to anchor the palladium nanoparticles, and the material was doped using KOH to form an ideal triple‐phase boundary structure around the palladium. The observed maximum power density is the highest among previously reported AEMFCs using palladium as the metal catalyst.
