In the proton exchange membrane fuel cell, the main function of the gas diffusion layer is to support the catalyst, and to provide a channel for the gas involved in the reaction and the water produced, and it is one of the key components of the membrane electrode. The gas diffusion layer is mainly used
A new material titanium felt with a diameter of micrometers. It is made of metal titanium fiber by laying and sintering at high temperature. Titanium fiber felt has a three-dimensional network porous structure. Porosity and hole diameter are adjustable. Finally, it will obtain the best electrolytic performance during the electrolysis process. In the process of
Atualmente, no PEMEC, a camada de difusão de feltro de titânio líquido/gás (LGDL) está localizada entre a camada catalisadora (CL) e a camada coletora de corrente com campo de fluxo. Quanto à finalidade do LGDL de feltro de titânio, é transportar elétrons, calor e reagentes/produtos de e para o CL com perdas mínimas de corrente, térmicas e fluídicas.
