This portal page aggregates information relevant to UPS (Uninterruptible
Power Supply) Applications.
An uninterruptible power supply i.e. a device that ensures constant
delivery of electricity to an electrical load. A UPS can be standby (Backup
Power) or full time (Primary
Power). Standby UPS systems only kick in when the primary power supply
is interrupted. Full time UPS systems run constantly, juggling their power
supply to ensure that the supply of electrical power to the device it is
protecting is constant and uninterrupted.
There are an increasing number of
Commercially Available Fuel Cell UPS Systems for Communications & Telecoms
Applications on the market.

Benefits of Fuel Cells for the UPS (Uninterruptible
Power Supply) Applications
- Autonomy Fuel cells are able to operate as long
as there is available fuel, so whether an 8 hour, 1 day or 3 day extended
runtime is required, enough fuel can be stored onsite.
- Remote monitoring Fuel cells 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 fuel cells than for battery banks.
Fuel cells do not require cooling like batteries which eliminates the
need for spacious cooling systems.
- Fuels - The majority of these systems operate on
hydrogen (in this instance the only emission is water), which can
be generated from renewable sources (electrolysis)
or from reformed hydrocarbons (methanol,
ammonia and natural gas).
- Temperature tolerance unlike batteries, fuel
cells do not degrade a high temperatures and their range can be between
- 40°C and +50°C
- Integration fuel cell systems provided as either
a standalone unit similar in size to a small refrigerator (for applications
like base stations) or can be inserted in existing 19 racks
- Cost over the lifetime of the unit can offer
cost savings over existing technologies. This include: maintenance,
repairs, transport and disposal
- 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. Failures tend to be less
critical and easily dealt with.
- Environmental Unlike generators, 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
- Maintenance fuel cells have very few moving parts
which reduces the need for regular maintenance.
