Abstract:
<p>This report endeavours to understand the technical aspects of a 5kW fuel cell based UPS. Suitable testing is done to determine whether the performance of the system is equivalent to a battery based UPS. The Economic analysis deals with the feasibility of a fuel cell UPS is today's economy.</p> <p>Testing was then carried out to verify the operation of the fuel cell and establish weather performance was equivalent with battery-operated UPS. The influence of temperature and stack power over start-up time was studied. To establish the dynamic operation of the fuel cell, load-switching tests, both of active and reactive nature, were carried out. Consecutive runs of soak tests were done to verify long hours of operation.</p> <p>The fuel cell has proven capable to equal the performance of a battery bank, to the inverter and then AC load, the fuel cell is just a battery which never drains. Testing in lower operating temperatures has shown start up is not affected by long hours on non-operation. Though the optimum fuel cell stack an ambient temperature of less than 20°C. Start up is not affected when operated with active and reactive loads.</p>Publication Year:
