All equipment including fuel cells, valve blocks and gas equipment mounted inside corrosion resistant outdoor enclosures. The FC enclosure has a single point of interface for all connections. DC power is delivered from the cabinet to the telcom tower at -48VDC.
Hydrogen storage cylinders mounted in a secure, outdoor enclosure. The cylinders are connected to a common gas manifold and then fuel is delivered to the fuel cell at reduced pressure. Each cylinder provides ~14 hours of runtime at the expected DC load of ~700W. With all 16 cylinders installed, the site can run for ~10 to 12 days depending on the exact load. Hydrogen supply and system maintenance included in the turn-key solution.
