GM expects fuel-cell vehicles to be commercially viable by that year, GM said in a statement, quoting Larry Burns, vice president of research and development, and planning.

"That means providing the customer with exciting, compelling vehicles at a price they can afford and one that makes sound business sense for GM," he was quoted as saying.

The statement was released as GM launched a weeklong demonstration of its environmentally-friendly technologies developed with its Japanese partners -- Isuzu, Suzuki and Fuji Heavy Industries.
