Fuel cell backup power systems integrated with electrolyzers for on site generation of hydrogen can provide reliable, grid independent and non fossil fuel dependant backup power in applications such as telecoms base stations.
Proton Energy system is interested to work with fuel cell developers to integrate their fuel cell systems and it’s HOGEN® HP High Pressure electrolyser into a single unit for backup power applications.
HOGEN® HP High Pressure Electrolyzers
- H2 output pressure: 2400 psi
- Hydrogen Production: 0.57 to 2.28 kg/24hr
- PEM - Caustic free
- Compressor free
- Low maintenance
- Fully automated System Integration

When grid power is available, the HOGEN HP recharges the hydrogen storage.
When grid power is lost, the stored hydrogen is directed to a fuel cell, which provides backup power to the load.
Applications
- Base stations
- Data centers
- IT security
- Remote transmission stations
Advantages of Regenerative Fuel Cell Backup Power Systems
- Autonomy – Fuel cells are able to operate as long as there is available fuel, and the system can be designed to store enough hydrogen for the required runtime.
- Remote monitoring – The system can be fully monitored from one central location alerting the operator as to when the system is in use and how long before refuelling is required to ensure no downtime.
- Footprint –The space required for the same period of runtime is considerably less for regenerative fuel cell units than for battery banks. Fuel cells do not require cooling like batteries which eliminates the need for spacious cooling systems.
- Hydrogen is generated on site via electrolysis to provide an autonomous and rechargeable energy storage system free from the encumbrances of delivered hydrogen.
- Temperature tolerance – unlike batteries, fuel cells do not degrade a high temperatures and their range can be between - 40°C and +50°C.
- Integration – RFC systems can be provided as either a standalone unit (for applications like base stations) or can be integrated into existing rack systems.
- Cost – Over the lifetime of the system, RFC’s offer cost savings over existing technologies. This includes maintenance, repairs, transport, and disposal costs.
- Reliability - In many cases, fuel cells are able to offer higher reliability and MTBF (Mean Time Between Failures) and there is no degradation of voltage over time.
- Environmental – Unlike generators, hydrogen fuel cells do not use combustion and therefore there are no NOx, SOx or particulate emissions from the unit. These characteristics can reduce complications with site placement and integration.
