Room-temperature synthesis produces hollow nanodome catalyst, slashing fuel cell costs and extending life Hydrogen fuel cells commonly use expensive metals like platinum, otherwise, they're ideal for green energy storage, and you can use them for anything, while they were originally developed for astronauts in orbit. About the only other technology that comes close is supercapacitors, which are only now beginning to mature. Its one thing to say we'll eventually replace the heavy battery in your laptop with a piece of carbon paper, and another to say they can replace all the batteries in a car with carbon paper. Your average car battery, just one battery, weighs 40-60lbs, and there's no doubt all the toxic batteries we produce must be replaced in the near future.
