摘要：

An effect of a micro porous layer (MPL) on water transport under a low-humidity condition was examined in a PEMFC with a single straight channel. using a tunable diode laser absorption spectroscopy (TDLAS) measurement system, which can measure local through-plane water transport based on measurement of the distribution of water vapor concentration along the channel. The TDLAS results showed that the MPL imparts mass transport resistance at the cathode side under low-humidity conditions with co-flow and counter-flow modes and enhanced back-diffusion of the generated water to the anode side. The MPL at the cathode side strongly affected through-plane water transport and is therefore effective for membrane hydration under low-humidity conditions.
