Plug Power to integrate Maxwell’s ultracapacitors into its fuel cell systems

Plug Power Inc. has selected Maxwell’s Boostcap ultracapacitors to enhance performance and energy management in its line of GenDrive power units.

The company, an integrator of fuel cell-based power solutions for zero-emission material handling vehicles, has finalised a purchase order for Maxwell’s Boostcap MC2600 2,600-farad ultracapacitor cells.

According to Maxwell, the combination of technologies is another example of the synergy between hydrogen fuel cells’ extended energy output and ultracapacitors’ short duration burst power capabilities.

Andy Marsh, president and chief executive officer, Plug Power Inc. said that GenDrive power units provide a high-efficiency, low-maintenance “drop-in” replacement for lead-acid battery packs in electric lift trucks. The GenDrive system delivers enhanced productivity by eliminating the downtime associated with the changing and charging of lead-acid batteries.

On decision to integrate Maxwell’s ultracapacitors into its fuel cell systems, Marsh said ultracapacitors’ burst power capabilities for lifting, as well as regenerative braking for energy recuperation and longer operating life make them an ideal complement to hydrogen fuel cells in this application.
