A 1 kW proton exchange membrane (PEM) fuel cell power system with heat and water recovery was successfully integrated. This power generation system is designed for the stationary application. The waste heat can be recovered into hot water, which store in a tank with temperature higher than 60°C. This hot water may be suitable for bath and kitchen use in a small family. The adjustment for the power generation system is now on going and promoting. Now 38% in the electrical efficiency (AC110V output) for the system is achieved. With waste heat recovery involved, the system will potentially have overall energy efficiency more than 70%. In order to optimize the system, some technologies should be studied and pre-tested before integration work, which mainly included water management for the fuel cell stack, water and thermal conditions on the performance of fuel cell, air and water pumping power needed for the fitting of optimum system performance.

Power generation using waste heat from cement kiln can not only bring economic benefits to the enterprise, but also play an important role in environment protection. Constantly researches have proved that there is still large energy saving potential in its operation. In this paper, the waste heat power generation system was divided into several subsystems, and the exergy calculation model of each subsystem unit was established. Finally, the weakest part in energy use was found according to the results. It provides a scientific basis for performance improvement and energy saving transformation of waste heat power generation.

In order to investigate the feasibility of a combined heating, cooling, and power generation system in the residential sector, an integrated system was designed and installed at the Archetype Sustainable House (ASH) of the Toronto and Region Conservation Authority (TRCA). A Stirling engine based cogeneration unit was used to produce the thermal energy for a thermally driven chiller. The engine supplies hot water up to 95°C. The overall efficiency of up to 90% is determined for the cogeneration system. A thermo-chemical accumulator provided by the ClimateWell AB, was installed and connected to the cogeneration unit. The experimental coefficient of performance (COP) of this chiller during the test period was less than 0.4. Since the ClimateWell chiller rejects heat during both charging and discharging processes, a heat recovery system using three cascade tanks and an outdoor fan coil was designed and installed to utilize the waste heat, for domestic hot water production. A complete TRNSYS model of the tri-generation system was used to verify the experimental results.
