New Cheaper Platinum Free Hydrogen Fuel Cell Announced
April 26, 2022 | Leave a Comment
Imperial College London researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum that should enable greater use of the technology. Hydrogen fuel cells convert hydrogen to electricity with water vapor as the only by-product, making them an attractive green alternative for portable power, particularly for vehicles. However, their […]
