Compact hydrogen fuel cell for portable electric power to release spring 2013

“Rohm, together with Aqua Fairy and Kyoto University, has developed a compact, high-output hydrogen fuel cell.
This fuel cell generates electricity by producing hydrogen on the spot. This is achieved through a chemical reaction between calcium hydride sheets and water.
From a sheet with volume of less than 3 cc, this fuel cell can generate 5 Whr of electricity. It can be used for many purposes, from charging a smartphone, to providing back-up power in emergencies.”
