Since fuel cell systems are an emerging technology, studies to develop alternative materials for fuel cell components are of great importance. In this study, the usability of stainless-steel metal mesh material was tested as diffusion layer (DL) for DBHFC, experimentally. The catalyst coated diffusion layer was obtained by coating the stainless steel meshes at different wire diameters, surface area, and opening ratio with palladium by the electrodeposition method. The newly developed DL was tested in a single cell experimental setup, which has a 2 × 2 cm2 active area. It has been observed that the cell with DL, where the wire diameter is high, has a relatively higher performance. Metal mesh DL, which is quite inexpensive compared to carbon-based DL material, achieves power outputs of up to 3.14 mW/cm2. Results showed that metal mesh material could be used as an alternative DL material for the fuel cell.
