New energy PEM hydrogen production porous titanium plate

The raw material of the porous titanium plate for hydrogen production by PEM water electrolysis is pure titanium powder, which is formed by pressing the mold and sintered at high temperature in a vacuum.

Hydrogen production by water electrolysis is a new energy pillar sunrise industry. The micropore diameter of the porous titanium plate is used to fully react with the medium to produce hydrogen energy. The surface is coated to prevent oxidation and increase the efficiency of hydrogen production. Porous titanium plates are widely used in hydrogen energy, petrochemical, and rmaceutical filtration, with obvious advantages, and are indispensable products.

Applications

The porous titanium plate is used as the GDLÂ (gas diffusion layer) of the anode for hydrogen production by water electrolysis in PEM water electrolysis. The pores are uniform and the porosity can be controlled at 30%-40%. Good electrical conductivity and strong corrosion resistance. It can be coated with platinum group metals to enhance its catalytic performance. The cost is relatively high, but the hydrogen production efficiency is high and the purity is high, which is suitable for industrial hydrogen production.

Every kind of filter material will be blocked, so it is very important to choose the pore size. If you choose the right pore size, you will have good filtration efficiency, and the blocking situation will be alleviated. If the blockage is serious, a regular replacement can solve this problem.
