Chemical reactions that help a gadget can now be run by a hydrogen fuel cell that uses enzymes and not expensive metal catalysts. Yes, you read it right. It is enzyme powered hydrogen fuel.
Making these fuel cells could be smaller, simpler and cheaper, compared to the conventional ones, according to the researchers. They have already gone innovative powering a digital watch using this fuel.
The hydrogen fuel cells are environment friendly, as they not only require hydrogen and oxygen to produce electricity, but also generate only water as a waste product. So, with it there is no adding of toxic emissions to the already polluted atmosphere. It is surely an eco-responsible and economy-efficient alternative to conventional batteries. It can hit the market as an excellent alternative to portable-gadget batteries.
