Virtues of splitting up water-splitting [PDF]

open access: yesScience, 2017
Electrochemistry Widespread use of solar power will require a convenient means of storing energy for use at night and on rainy days, and making hydrogen fuel from water is a clean prospective solution. Most current approaches split the water into hydrogen and oxygen in the same apparatus, with a membrane keeping the two mutually explosive gases apart ...
