摘要：
An excellent hybrid proton exchange membrane (PEM) is prepared using a one-step synthesis to anchor phosphotungstic acid (HPW) into a polyvinylpyrrolidone (PVP) matrix. The hybrid membrane exhibits high proton conductivity and excellent stability. The impressive performance of a single cell based on the hybrid membrane, with a power density of 618 mW cm-2 at 50° C, demonstrates promising potential for application in fuel cells. © 2014 WILEY-VCH Verlag GmbH & Co.
