Engineered water highways to improve fuel cell efficiency

Researchers at the Paul Scherrer Institute (PSI) have developed a coating technique that improves water management in fuel cells, thus raising their efficiency. The technique is suitable for mass production, e.g. in a roll-to-roll process. It consists of creating nearly straight hydrophilic pathways in the gas diffusion layer (GDL) of a fuel cell by means of radiation grafting. The hydrophilic water pathways improve the performance of the fuel cell by rendering the pathways for gas transport through the GDL less tortuous.
