Abstract

We develop a facile and eco-friendly airbrush-based method for the fabrication of gas diffusion layers (GDLs) with improved water removal characteristics for high-performance polymer electrolyte membrane fuel cells (PEMFCs). The GDL architecture airbrushed on a porous carbon paper uniquely comprises hydrophobic double-layer coating and fine-patterned hydrophilic channels, which facilitate the outbound penetration of water generated from inside the membrane electrode assembly without flooding or undesirable mingling with oxygen inflow. We first prepare the colloids and solutions suitable for airbrushing, optimize the airbrush coating structure based on the water contact angle measurements, and finally confirm the improved water removal characteristics of the fabricated GDL samples by measuring the water transuding times. Our GDL fabrication procedure based on simple and fast airbrushing does not require costly vacuum process or toxic chemical treatment, thus may benefit practical and scalable manufacturing of high-performance PEMFCs towards the next-generation green transportation.
