Fuel Cell Uninterruptible Power Supply

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.

Fuel cell uninterruptible power supply.

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. Hydrogen offers a better solution. Designed to be extremely reliable the gencell solution has minimal moving parts. A three port bidirectional converter connects a fuel cell and a supercapacitor to a grid interfacing.

Keywords fuel cell supercapacitors dc dc conversion uninterruptible power supply i. With an uninterruptible power system the limitations of traditional storage systems and generators have now been overcome. Backup power systems incorporating hydrogenics hypm xr fuel cell power modules offer consistent power seamless switching and virtually limitless runtime. Unigen regenerative fuel cell for uninterruptible power supply author.

This paper proposes a line interactive fuel cell powered uninterruptible power supply system. An energy storage system ess is made of homogenous ess devices organized to provide the demanded power and the rated voltage. 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. Introduction uninterruptible power supplies ups provide highquality and reliable backup power.

Clean power net the clean power net cpn strategic partnership was established in august 2011. Uninterrupted power supply ups and telecom backup power. 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. Hydrogen fuel cells offer reliability and a smaller carbon footprint compared to diesel and battery systems.

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. 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. 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 fuel cell systems operate.

The drawbacks are inconsistent power limited runtime physical plant issues and high maintenance.
