Abstract

Due to environmiiiental concerns and limiited hydrocarbon fuel reserves, R&D effort is being put into alternative energy sources liLce geothennal, photovoltaic, wave and wind, as welL as fuel cells which use hydrogen to generate electricity without increasing pollution. Fuel cells for a residential application, with combined heat and power (CHP), may offer a viable energy source when both thermal and eloctrical outputs are associated with energy storage. The addition of grid connection improves reliability and offers the option to sell surplus energy when economically justified. A fuel celL has a variable, low voltage dc output requiring a power electronic interface to any energy storage and to ac loads. A simple inverter topology can be adopted based on minimum component count. This paper presents the design, simulation and experimental verification of an cconomic arrangement utilising an intormecdiate voltage storage battery and a bicdirectional dcac interface suitable for domestic ac loads and grid synchronisation. The design was modelled in Matlab/Simulink. An economic model of the fuel celllbattemy/grid system. operating in micro-CBP mode, was developed to assess the prospects for commercial exploitation and to characterise the relationship between domostic load profile, fuel cell rating and battery capacity to optimize life time
cost. This modol assumes natural gas for the fuel celL as hydrogon infrastructure is not yot available. The economic model results and their interpretation will be the subject of a future publication.
