Facilitating the Mass Transport in Gas Diffusion Layer of PEMFC by Appling Dry-Layer Preparation of Micro Porous Layer

PEMFC is an important technology as potential power sources. Over the past several years, applications of this technology has been successfully demonstrated in a wide variety of fields including transportation power, hybrid heat/electricity supply for buildings and distributed generation, etc. However, reliability, cost,durability and operational flexibility of PEMFC still remain the hurdles to its commercialization and should be greatly improved to promote the practical application of this technology. The development of the key material on which the success of the PEM fuel cell technology hinges-namely, the PEMs should be given highly emphasis on.
