A portable device creates green electricity through fuel cell energy

Billing itself as “the world’s smallest pocket sized fuel cell charger,” JAQ wants to free device users from the constraints of a wall outlet by using green electricity. The reaction between salt water and oxygen lets you charge your phone in a subtle and clever way.

From the outside, JAQ looks almost like an average phone case. But its contents are key to the way that JAQ differs from your average mobile charger.

Since it might seem difficult to understand how a charger could work using only salt water and oxygen, JAQ maker myFC gives a pretty detailed breakdown on the power of fuel cell energy. The gist: products like JAQ harness the ability of fuel cells to transform hydrogen into electricity. In this case, JAQ uses salt and water as an “external supply of fuel” and oxygen as an oxidant. The chemical reaction between hydrogen and oxygen results in green electricity.
