Fuel cells with PFIA-membranes

Scientists are exploring water management in an alternative proton exchange membrane type, called PFIA. The experiments have been conducted using the infrared facilities of BESSY II synchrotron to reveal how water is retained even at dry conditions in PFIA. The observations explain why PFIA membranes are superior to the widely used NAFIONTM membranes at higher temperatures and low humidity.
