David Schramm, Maxwell's president and chief executive officer, said that Plug Power has placed a purchase order for Maxwell's BOOSTCAP MC2600 2,600-farad ultracapacitor cells to be delivered during the third and fourth quarters.

"Plug Power is a leading integrator of fuel cell-based power solutions for zero-emission material handling vehicles, such as electric lift trucks, as well as other continuous and backup power applications," Schramm said. "This innovative 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, Plug Power's president and chief executive officer, 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.

"Productivity drives purchasing decisions in the material handling industry," Marsh said. "Integrating Maxwell's ultracapacitors into our fuel cell systems enhances the value of our GenDrive product for our customers. 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."
