Understanding the gas diffusion layer in proton exchange membrane fuel cells. I. How its structural characteristics affect diffusion and performance

The proton exchange membrane fuel cell (PEMFC) has a significant potential in transportation, backup, and portable power applications, although there still are remaining technical and cost challenges. A key current goal is improving the performance while reducing the cost of the gas diffusion layer...
