Abstract
An electrode for a fuel cell system is provided. The electrode includes a carbon support. Platinum-based catalyst nanoparticles are dispersed on the carbon support. Zirconium-based dopants are disposed on the carbon support. In one example, a fuel cell system includes the electrode as a first electrode and further includes a second electrode and a fuel cell membrane. The fuel cell membrane is disposed between the first and second electrodes.
