Plug Power Inc.’s GenDrive 1900 hydrogen fuel cell is designed as a drop-in replacement for lead-acid batteries on six-ton capacity, four-wheel, class-one counterbalanced forklift trucks. An optional second hydrogen tank doubles hydrogen capacity. With both tanks installed, the fuel cell can store up to 3.4 kg of hydrogen with an energy capacity of 50 kilowatt-hours (kWhr). Capable of a constant power output of 14kW, the fuel cell delivers more than eight hours of runtime, which is 50% more than a conventional battery in this application. The GenDrive 1900 has a refill time of two minutes, maximizing the productivity of forklift trucks.
