East Japan Railway Co., the world’s largest passenger railway company, will shortly complete a prototype fuel-cell train for test runs, the Jiji Press news agency said.
The test train will be made up of a single car and carry two 65-kilowatt fuel cells, the report said. It can travel at 100 kilometers (62.5 miles) per hour.
No official was immediately available at the company to confirm the report.
Fuel cells produce electricity through a chemical reaction between hydrogen and oxygen, leaving water as the only by-product.
Fuel-cell batteries in cartridges can be easily replaced in contrast to conventional batteries that take hours to recharge.
The company plans to operate fuel-cell trains sometime in mid-2007 on its lines in mountain regions west of Tokyo, the report said.
