Hydrogen is widely used to industries of petroleum, chemistry, metallurgy and electronics,etc. Hydrogen generation system by water electrolysis is one of the important hydrogen production methods.
Why Titanium for hydrogen? The reason for titanium is its safety, strength, hardness, and ability to resist erosion. Using Titanium allows for a strong, durable, erosion-resistant plate with the least possible mass [i.e., thin, yet super strong]. For these reasons titanium is used in bone and joint replacements. Titanium is also used in space shuttles. No other metal is better than titanium for use with water ionizer plate construction.
The Sintered Titanium Felt is the best material.
