TreadStone has developed low cost coating technologies for PEM fuel cell and electrolyzer applications. The coating technology using precious metal has a unique design and processing technique for cost reduction, while meet metal plate's technical requirements. - The technology has been demonstrated in 2,000 hours stable operation in automobile PEM FC operation conditions. - The technology has also been demonstrated for PEM electrolyzers and redox batteries for energy storage applications. The coating technology without using precious metal (doped titanium oxide coating) has demonstrated the feasibility for PEM fuel cell applications: - Demonstrated superior corrosion resistance and performance stability in ex-situ corrosion tests and single fuel cell test. - The demonstration in automobile fuel cell stack is on-going at Univ. Hawaii. - The doped titanium oxide coating has the potential for PEM electrolyzer applications due to is superior stability at high potential. TreadStone is actively looking for production partners to scale up and commercialize these technologies.
