Abstract:Hydrogen fuel cells based on proton exchange membrane (PEM) technology are promising as an alternative to fossil fuel-based energy. Conventional PEMFC technology is operated at fully humidified conditions in a narrow temperature range (~ 80 oC) to maintain sufficient proton conductivity and power output, which necessitates high cost of operation. In this work, we demonstrate a scalable, room temperature coating of ultrathin boron nitride (BN) via pulsed laser deposition (PLD) that simultaneously increases cond… Show more
