This study developed a self-humidifying membrane electrode assembly (MEA) in a proton exchange membrane fuel cell to simplify the requirement for external gas humidification of the fuel cell system. An electrospinning technique was used to synthesise the hydrophilic titanium dioxide (TiO2) nanofibers. The synthesised nanofibers were used in catalyst layers of anodes to absorb the water diffusing from the cell cathodes. Two processes were used to prepare the self-humidifying MEA. First, TiO2-loaded Pt/C catalyst ink was directly coated onto the gas diffusion layer to form a gas diffusion electrode. Second, a transfer method was used to fabricate a catalyst-coated membrane. Scanning electron microscopy, X-ray diffraction, and a water contact angle test were used to characterise the TiO2 nanofibers and catalyst layer. Anatase TiO2 nanofibers with diameters of approximately 25 nm were successfully synthesised. The IV performance test results show that adding electrospun TiO2 nanofibers improves fuel cell performance under low- or zero-humidification conditions at a fuel cell temperature of 50 °C.
