MISSISSAUGA, Ontario, Dec. 5, 2012 -- Hydrogenics

Corporation (Nasdaq:HYGS) (TSX:HYG), a leading developer and manufacturer of
hydrogen generation and hydrogen-based power modules, announced that it
received an order for the delivery of HyPM(TM) XR Series fuel cell power
modules from its US-based partner, CommScope, Inc.

Hydrogenics power modules will be integrated into CommScope's fuel cell
cabinets as the backup power solution for hundreds of wireless sites in
North America, servicing a leading wireless operator. This is the largest
single order from CommScope since the announcement of the strategic alliance
between CommScope and Hydrogenics in 2010. This award is significant as it
brings total orders in the Hydrogenics power systems business to over $100
million for 2012.

"We are very pleased with this order from CommScope for one of their key
customers in North America," said Daryl Wilson, Hydrogenics'
President and Chief Executive Officer. "CommScope is a leader in providing
communications infrastructure solutions to world's largest telecom players,
and hydrogen backup power cabinets provide a clean, reliable, long-term
energy source to cell sites while avoiding the inherent issues and costs
associated with batteries and diesel generators. We have worked closely with
CommScope to develop and launch a best-in-class outdoor backup power
solution for telecom customers.
This year we have seen increased interest for the CommScope/Hydrogenics
back-up power package from telecom players around the globe, and we
