|The fuel-cell hybrid Midi-bus for Barth.|
Proton Motor Fuel Cell GmbH (PM) recently delivered one of its first fuel-cell hybrid buses to the City of Barth, Germany (Mecklenburg-Vorpommern).
Proton has delivered a few other fuel-cell buses, but each powertrain is as yet a one-off solution. The company, according to Dr. Joachim Kroemer, Head of Sales, will introduce a series-type fuel-cell bus next year.

The Barth Midi-bus uses six PM 600 fuel-cell stacks to deliver 45 kW of rated power (maximum power of 60 kW) to twin traction motors. A NiMH battery pack provides energy storage for regenerative braking. Total drivetrain power is 80 kW. Two tanks store compressed hydrogen at 200 bar and hold a total of 320 liters of hydrogen per tank.
The fuel-cell bus carries 22 passengers and has a maximum speed of 70 kph (43.5 mph) and has a range of 180 km (112 miles).
