Nippon Telegraph and Telephone Corporation have developed a prototype micro polymer-electrolyte fuel cell (PEFC)1 that uses hydrogen gas as a fuel and is small enough to directly fit in a mobile phone. Under tests using a production-model mobile phone, this prototype PEFC successfully powered start-up and signal reception/transmission (i.e., video phone, voice calls, and "i-mode" internet services). In conjunction with this development, we also developed a device for automatically topping up the micro PEFC with hydrogen.

The exhaust gives out water (vapor).

Mix Hydrogen gas with electricty and hold it next to your ear.
I can think of a few people whom I'd like to give a phone like that...

Unless there was an internal storage tank for the water.
