Abstract
\n<\/span><\/p>\n

The performance of the\u00a0electrospray<\/span><\/a>\u00a0technique was applied to obtain a\u00a0gas diffusion<\/span><\/a>\u00a0layer (GDL) for a proton exchange membrane\u00a0fuel cell<\/span><\/a>. It was confirmed by\u00a0confocal microscopy<\/span><\/a>\u00a0that polytetrafluorethylene (PTFE) was impregnated into the backbone, forming a dispersed layer of microscopic size homogeneously distributed over the substrate. The PTFE layer was characterized by infrared spectroscopy and\u00a0thermogravimetric analysis<\/span><\/a>. In this work, we demonstrated that the use of the GDL prepared by electrospray increases the maximum power of the H<\/span>2<\/sub><\/span>\/O<\/span>2<\/sub><\/span>\u00a0fuel cell by about 10%\u00a0and decreases the diffusion loss of the\u00a0electrode<\/span><\/a>\u00a0owing to a better distribution characteristic hydrophobic coating with low impedance to gas diffusion. Thus, our method is promising for the development of fuel cells by the production of\u00a0diffusion layers<\/span><\/a>.
