Abstract

Porous carbon materials, which are widely used as gas diffusion layer (GDL) in PEFCs, have several issues including high cost and mechanical strength. In order to reduce the cost and thickness of GDLs, we focus on the possible use of metallic Ti and Sn as alternative GDL materials. In this study, Sn/Ti and Sn/Sn GDLs are prepared, which are based on porous Ti or Sn plates coated with Sn layer. Microstructural observations using scanning electron microscope (SEM) confirmed that porous Sn dendrite layer could be formed on the metallic GDLs. Current-voltage measurements of the cells using these materials revealed that the porous structure of the GDLs, on which Sn dendrites were formed, is advantageous to improve electrical contact.
