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

At the present time, in the PEMEC, titanium felt liquid/gas diffusion layer (LGDL) is located between the catalyst layer (CL) and current collecting layer with flow field. As for the purpose of the Titanium felt LGDL, is to transport electrons, heat, and reactants/products to and from the CL with minimal current, thermal, and fluidic losses.
