Low platinum fuel cells for hydrogen vehicles New research from Sweden suggests that low platinum fuel cells for hydrogen vehicles, when scaled up for the same number of cells, may achieve similar or higher efficiencies compared to commercial fuel cells. Their modeling is expected to act as a bridge between material science research and vehicle implementation.
