As far back as 1839, the English scientist William Grove had the idea that the reactants of a battery could be gases fed into it from external tanks. For most of their history, fuel cells existed only as laboratory curiosities. But fuel cells have gained much more attention in recent years, with many considering these power sources for applications in vehicles and alternative grid technology.
New research from Harvard University shows just how promising fuel cell technology could be. According to the study, the researchers were able to develop more efficient fuel cells that get more robust as they age instead of degrading.
