Fuel Cell Uninterruptible Power Supply

With an uninterruptible power system the limitations of traditional storage systems and generators have now been overcome.

Fuel cell uninterruptible power supply. This paper proposes a line interactive fuel cell powered uninterruptible power supply system. Hydrogen fuel cells offer reliability and a smaller carbon footprint compared to diesel and battery systems. Two commercially available proton exchange membrane fuel cell 25 39 v 500 w modules together with suitable dc dc and dc ac power electronic converter modules are employed. The drawbacks are inconsistent power limited runtime physical plant issues and high maintenance.

Keywords fuel cell supercapacitors dc dc conversion uninterruptible power supply i. Introduction uninterruptible power supplies ups provide highquality and reliable backup power. Hydrogen offers a better solution. A ups differs from an auxiliary or emergency power system or standby generator in that it will provide near instantaneous protection from input power interruptions by supplying energy stored in batteries.

Designed to be extremely reliable the gencell solution has minimal moving parts. The gencell g5 long duration ups uninterruptible power supply provides a potentially unlimited source of 5kw backup power along with support for peak loads of up to 100kva for a wide range of markets from commercial and industrial applications to first responders and defense telecom and other segments. An uninterruptible power supply or uninterruptible power source ups is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A 1 kva fuel cell powered line interactive uninterruptible power supply ups system that employs modular fuel cell and power converter blocks is introduced.

Hydrogen uninterruptible power supply. Hydrogen fuel cell systems operate. Cts energy has designed solutions for the safety of your electronic systems managing the numerous benefits of a fuel cell applied to a back up system that produces electricity.

Clean power net the clean power net cpn strategic partnership was established in august 2011. Consisting of 20 industrial enterprises and research institutions the group signed a memorandum of understanding concerning the market preparation of fuel cells for deployment in uninterruptible power supply systems. Proton fuel cell presentation for the 2004 hydrogen fuel cells infrastructure technologies program annual review held in philadelphia pa may 24 27 2004 created date. An energy storage system ess is made of homogenous ess devices organized to provide the demanded power and the rated voltage.

A three port bidirectional converter connects a fuel cell and a supercapacitor to a grid interfacing.
