Affordable solar storage is one step closer to us.
The electricity generated by the solar panels during the day can remove moisture into oxygen and hydrogen and then be used at night to power the fuel cell.
Water is usually broken down using electrolysis, but the cost is high.
Now, Daniel Nocera of MIT has made a cheaper device by depositing cobalt and phosphate on the oxidized indium tin electrode.
These chemicals catalytic water
Splitting the reaction, so it takes less power to produce the same amount of oxygen.
