Fuel cells provide no-maintenance power

The logistics problems are sometimes monumental. Pressure is mounting to reduce costs and boost efficiency. The EFOY Pro presents an attractive, low-maintenance alternative for reliably powering remote telecommunications and metering equipment such as:

• level gauges used in flood and tsunami early-warning systems
• water-quality meters
• biological and geological instruments
• remote servicing stations
• vehicle-based measurement instruments
• electromagnetic-wave meters
• digital BOS transmission/TETRA etc.

EFOY fuel cells are at work today providing clean, reliable energy to numerous environmental sensors and telecommunications facilities located in remote areas. There’s less need to travel long distances to replace batteries or refuel generators, which in turn reduces costs and protects the environment.

A practical example

Before: No EFOY Pro fuel cell
For example, a 10-watt level sensor requires 240 watt hours per day for continuous operation. A 60 Ah lead-acid battery can supply enough power for three days. To replace the battery from a base camp 100 km away will cost 200 km @ 0.40 EUR or 80 euros. Add to that two-and-a-half hours of wages @ 85, or 215 euros. The total cost per trip is thus approx. 300 EUR. In the above example, that would mean 700 EUR worth of costs every week.

Many cases, however, involve a lot more travel. Some metering devices located in nature preserves or along oil and gas pipelines are only reachable by helicopter. The cost here: 5,000 EUR per hour!
The bottom line is: difficult logistics, long distances, and considerable costs.

After: With an EFOY Pro fuel cell
One EFOY Pro equipped with an M28 EFOY fuel cartridge will power the level sensor for 130 days – nearly 4 ½ months – reliably, quietly, cleanly, and completely maintenance-free.
