A prototype of an innovative folding hydrogen-powered bicycle has officially rolled off the production line in the city of Changzhou, east China's Jiangsu Province, according to its developer on Friday.

The bike has a similar shape to conventional bikes, but it's equipped with a hydrogen fuel cell and a low-pressure hydrogen storage device. The cell generates power to drive the bike once its proton exchange membrane receives hydrogen from the hydrogen storage device.

Compared with conventional electric bikes that use lithium batteries, the hydrogen fuel cell features several advantages including a longer service life, and it is more environmentally-friendly as it only produces water during operation.
