Fuel cells are far greener than gas-powered engines because they produce electricity without burning up the hydrogen (or other fuel) that powers them. But they’re often impractical on a commercial scale because they’re so much more expensive to make. Now, researchers report that by creating a fuel cell that can run at a midrange temperature, they’ve made an inexpensive, powerful version that could boost the prospects for plentiful green energy.
