A British company is working with Apple and has created a hydrogen fuel cell for an iPhone 6 that will last a week without recharging.

Analytical studies shows that Intelligent energy has created iPhone 6 prototype that only differs from other iPhone 6 in having tiny vents in the rear that allows imperceptible amounts of water vapors to escape. The prototype contains both hydrogen fuel and a rechargeable battery.

Hydrogen fuel cells generate energy by combining hydrogen and oxygen by emitting water molecule. Fuel cells supply hydrogen to a negative anode (an electrode through which electrical current flows), releasing electrons. The electrons then flow to a positive cathode (another electrode) to generate electricity. In addition, after releasing electrons, the hydrogen becomes a hydrogen ion moving to positive cathode and bonding with oxygen in the air, forming water.

Mark Lawson-Statham, Intelligent Energy’s finance chief, told that the smartphone fuel cell technology is still a couple of years out from being commercialized.

Like other fuel cells, the one in iPhone 6 is recharged by hydrogen gas that is provided by adapted headphone socket.

Intelligent energy is now working on commercial cell phones and that would be in the form of small cartridge that fits in the bottom of the phone. The cartridge would supply power for a week and could be discarded after use.
