Abstract

Technology for fabricating porous current-conducting gas-diffusion supports for fuel element electrodes made of carbon-carbon composites with the structure of fabrics, knits, and nonwovens was developed. The process scheme for manufacturing gas-diffusion electrodes for fuel cells was examined. The properties of the gas-diffusion supports manufactured with the technology of the St. Petersburg State University of Technology and Design and supports from E-TEK (USA) were investigated and compared.
