AC Transit’s fuel cell bus breaks 25,000 hour operating record; demonstrating potential to meet diesel life cycle expectancy

Green Car Congress

Just two years ago, the FCEB power plant set an international record for 20,000 hours of continuous operation. Traditionally, a public transit buses life expectancy is measured in terms of the number of miles on its diesel engine. A diesel engine’s life expectancy is 6 years or 250,000 miles before overhaul.
