...AND CHEAPER...:

A team of researchers based in Europe has developed a hydrogen fuel cell that switches out rare and costly platinum and replaces it with iron, lowering one of the key barriers to a technology that many hope can help decarbonise heavy transport, shipping and aviation.

Hydrogen fuel cells convert hydrogen to electricity with water vapour as the only by-product, making them a sustainable alternative - as long as the hydrogen is sources from renewables - for portable power, particularly in vehicles.

Currently, however, fuel cells rely on a catalyst made of platinum, which is expensive and scarce - according to the researchers - and accounts for around 60% of the cost of a single fuel cell.
