Harvesting 'limitless' hydrogen from self-powered cells

US researchers say they have demonstrated how cells fuelled by bacteria can be "self-powered" and produce a limitless supply of hydrogen.

Until now, they explained, an external source of electricity was required in order to power the process.

However, the team added, the current cost of operating the new technology is too high to be used commercially.
