Mott Corporation

Mott specializes in sintering metal powders into rigid, porous structures with precisely controlled pore sizes — measured in microns or sub-micron ranges. The technology allows gases or liquids to pass through while trapping contaminants, or to diffuse uniformly into a process stream. This sintering capability underpins products for semiconductor gas filtration, electrolyzer porous transport layers, and implantable medical device venting.

Mott produces porous transport layers — titanium-based sintered components — for proton-exchange-membrane electrolyzers that produce green hydrogen. The firm's ability to control porosity at scale positions it as a direct supplier into the electrolyzer manufacturing ecosystem, which has drawn capital from infrastructure and energy-transition funds monitoring the hydrogen buildout.
