Polymer-dipped carbon nanotube catalysts equal or outperform platinum catalysts in fuel cells; potential for significant cost reduction

Green Car Congress

Researchers at Case Western University have developed catalysts made of carbon nanotubes dipped in a polymer solution that equal the energy output and otherwise outperform platinum catalysts in fuel cells. They’ve already shown the simple technique can significantly reduce fuel cell cost. Credit: ACS, Wang et al.

UK awards £28M for 5 demonstration-phase low-carbon hydrogen production projects

Green Car Congress

This technology could lower the cost of low carbon hydrogen by over 20% and has become the basis for the Department for Business, Energy and Industrial Strategy (BEIS) and the Committee on Climate Change’s (CCC) analysis. The project aims to reduce the cost of electrolytic hydrogen significantly. Led by Cranfield University.

ITM Power reports completion of HydroGEN alkaline electrolyzer project; prototype stack 43% the cost of its PEM counterpart

Green Car Congress

ITM Power reported that a recently completed three-year collaboration project co-funded by the UK Technology Strategy Board (TSB) resulted in a new alkaline solid polymer membrane for an electrolyzer. The alkaline environment enables alternative, lower cost non-precious metal catalyst materials to be used.

CMU researchers rule out one potential cause of resistance in polymer electrolyte fuel cells; R&D guidance toward commercialization

Green Car Congress

Researchers at Carnegie Mellon University have discovered how nanoscale polymer films limit future cost reductions in fuel cell electric vehicles. The large amount of platinum for the cathode forces the cost of the fuel cell system higher. The results were reported in a paper in the ACS journal Langmuir. —Liu et al.
