5 kW combined heat and power generator with PEM Fuel Cells
The goal of the project was to construct and test a 10 kW CHP (5 kWe) PEM FC generator aimed for single-family households in Denmark. Two generators, each 'half size' of the project generator goal-size, have been constructed instead. These two generators can be connected in parallel to yield the added power.
The aim of the present project is to develop, construct, and test a 5 kW_e fuel cell generator system designed for production of combined heat and power. The system design will be modular to allow test of different fuel cell types and fuel gas supply systems. The system will be designed, constructed, and tested by IRD in co-operation with APC-SILICON and Dansk Gasteknisk Center. The project is divided into two major phases. The first phase (3 years) concerns design, constructing, and test of a fuel cell generator using H_2_(_g_) as fuel. The second phase includes design, construction, and test of a reformer system for the generator to use natural gas as fuel. Phase two will be planned in detail upon successful completion of the construction within phase 1 (present project). Stationary power systems are the future solution to the high distribution costs and the increasing need by commercial and industrial users for flexible, lower cost power. Typical applications are houses, office buildings and stores, hotels, and light industry
A substantial effort has been done within this project to develop individual BoP components that are not commercial available e.g. tailor made grid connected electronic inverters for FCs, and automated electronic control. Each FC generator has been integrated into standard sized cabinets (59 63 160/167 cm3). The 1 G generator does perform poorer than aimed, mainly because the PEM FC stack (alpha-design) used is intended for elevated pressure operation (2.5 bar(abs)), but operated at ambient pressure to lower the parasitic power spend by the air compressor. The 2G generator is equipped with IRDs beta-PEM stack design intended for operation at ambient pressure. This generator yields almost the desired power. The actual test time is lower than planned, because the long dynamic test were planned to be financed outside this project, and this possibility failed. The micro-CHPs have created a lot of attention. Both generators have been borrowed by several of IRDs partners for demonstration of the simplicity of the systems. Un-experienced operators could by pressing one bottom run the generator, after connecting the generator to hydrogen, cooling water, and the electrical grid
