The suports were also catalyzed by deposition of Pt and tested for its performance and electrochemical stability in RDE and fuel cell experiments. For testing the electrochemical stability and fuel cell performance of the catalysts and supports, we have employed the protocols in use at the Department of Energy and Nissan Technological Center North America (NTCNA).

Fuel Cell Vehicles: Challenges

2020/5/5Several challenges, technical and otherwise, must be overcome before fuel cell vehicles (FCVs) will be a successful, competitive alternative for consumers. Onboard Hydrogen Storage Some FCVs store enough hydrogen to travel as far as gasoline vehicles between fill-ups—about 300 miles—but the storage systems are still too large, heavy, and expensive.
