The reason for the low efficiency of hydrogen transportation is that the density of hydrogen storage is too low. At present, various methods of hydrogen transmission are actually transporting stored hydrogen. If the hydrogen storage density increases, the efficiency of hydrogen delivery will naturally increase. Scientists now boldly imagine the co-transmission of hydrogen and electricity,...

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...

Titanium fiber felt, a diffusion layer material, provides electrons between the catalyst layer and the bipolar plate or the current distributor on the anode side. Due to its three-dimensional network porous structure, high porosity, high corrosion resistance and other characteristics, titanium felt has become one of the best materials of diffusion layer in fuel cell...

À l'heure actuelle, dans le PEMEC, la couche de diffusion liquide/gaz (LGDL) en feutre de titane est située entre la couche de catalyseur (CL) et la couche collectrice de courant avec champ d'écoulement. L'objectif de la couche de diffusion liquide/gaz en feutre de titane est de transporter les électrons, la chaleur et les réactifs/produits vers et depuis la couche de catalyseur avec un minimum de pertes de courant, thermiques et fluidiques.....
