Dimensionally Stable Cross-Linked Hydroxyl-Functionalized Sulfonated Poly(ether ether ketone) with Low H2 Crossover and High Proton Conductivity for High-Performance H2 Sensing.

Reliable H2 leak detection is essential because H2 is highly diffusive and flammable. Although fuel-cell H2 sensors are attractive for room-temperature operation without external bias, their performance is limited by conventional proton exchange membranes (PEMs) such as Nafion, in which high H2 crossover and excessive...
