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...

As the global resource shortage is becoming more and more serious. In terms of new energy, especially the process of producing hydrogen from electrolyzed water. Many customers demand metal fiber felts with a thickness of 200-240 microns and a porosity of 70%. Titanium felt is essential for Electrolysis hydrogen production equipment. Due to the high...

Un nouveau matériau, le feutre de titane, d'un diamètre de quelques micromètres. Il est constitué de fibres de titane métallique par pose et frittage à haute température. Le feutre en fibres de titane présente une structure poreuse en réseau tridimensionnel. La porosité et le diamètre des trous sont réglables. Enfin, il obtiendra les meilleures performances électrolytiques pendant le processus d'électrolyse. Dans le processus de...

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.....
