Maintenance-free power by using the fuel cell 

Both public and private road crews go to a lot of effort making sure that traffic flows safely around construction sites. That means either laying power cables at great expense or regularly replacing dead batteries with freshly charged ones.

Without fuel cells

A trailer carrying warning signals has to go back to the shop for recharging every eight hours. In the meantime, another one has to be towed out to the roadwork site.

That means high costs, lots of travel and constant exposure of workers to traffic hazards.

The Solution: Low-maintenance power from a fuel cell

The EFOY Pro offers an attractive solution in view of the CO² discussion and calls to cut costs and heighten productivity. Fuel cells provide low-maintenance, reliable electrical power for remote traffic-control applications such as:

• alternating-traffic signs
• directional signals
• speed-limit signs
• blinkers in series
• warning-light trailers
• warning blinkers
