fuel cell
Fuel cell is a kind of power generation device, but it is not like a normal non-rechargeable battery and discarded when used up, nor is it like a rechargeable battery. To maintain its electricity, the fuel required is “hydrogen”, and this is why it is classified as a new energy source. Principle of fuel cells...

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...

At present, hydrogen production mainly contains four processes and technologies:1. Electrolysis of water; 2. Fossil fuels; 3. Industrial by-products; 4. Biomass. Electrolysis of water can directly obtain fuel hydrogen without CO, but its high cost is not conducive to the widespread promotion of this technology. Although the cost of the three types of production technologies...

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....
