  "textContent": "A fuel cell membrane electrode assembly includes a substrate and a porous polymer membrane. The substrate includes a woven layer including a yarn of polyvinylidene fluoride (PVDF) fiber. The yarn is 7 to 25 denier. The substrate also includes a nanofiber layer including PVDF nanofibers deposited on the woven layer. The nanofiber layer is 1 to 10 micrometers (μm) thick. The substrate exhibits a porosity of at least 70 percent and is less than 30 μm thick. The porous polymer membrane is deposited on the nanofiber layer. The substrate is a porous support for a fuel cell membrane. A method of forming a fuel cell membrane electrode assembly includes weaving a woven layer of a yarn including fiber of PVDF. The method also includes depositing a nanofiber layer on the woven layer to form a substrate. The method further includes depositing a porous polymer membrane on the nanofiber layer.",
