Hydrogen Fuel Cells Could Get A Lot Cheaper With Newly Developed Iron Catalyst
The title of this post, is the same ass that of this article on Hydrogen Fuel News.
These are the first two paragraphs.
Scientists have been looking for an alternative to precious metals such as platinum for decades, in the hopes of bringing down the cost of hydrogen fuel cells.
An alternative to a platinum catalyst that costs considerably less will help to bring down the cost of hydrogen fuel cells and of using H2 as a carbon emission-free fuel. This would make it cheaper to both produce and use H2.
Researchers at the University of Buffalo, appear to be on the road to using iron as an affordable catalyst.
This paragraph describes he structure of the catalyst.
The researchers looked to iron because of its low cost and abundance. On its own, iron does not perform as well as platinum as a catalyst, particularly because it isn’t as durable in the face of highly corrosive and oxidative environments such as those within hydrogen fuel cells. The researchers bonded four nitrogen atoms to the iron in order to overcome that barrier, followed by embedding the material within a few graphene layers “with accurate atomic control of local geometric and chemical structures,” said Wu.
Gang Wu is leading the research.
In the early 1970s, I worked with one of ICI’s catalyst experts and he said, that improvements in this area will be large in the future.
Increasingly, I see his prediction being proved right, in the varied fields, where catalysts are used.
