碩士 === 國立臺南大學 === 綠色能源科技研究所碩士班 === 98 === The purpose of this thesis is to design, fabrication, and testing a prototype of a PEM fuel cell co-generator with high-quality electricity and hot water. The first is to build the subsystems of the fuel cell co-generator, temperature control subsystem. Then, a microcontroller of the co-generator is developed and integration of the fuel cell co-generator is completed. Meanwhile, optimal control strategies for operation of the co-generator are proposed. Finally, parametric studies on the dynamic behaviors and efficiencies of the co-generator are presented, including office electricity use, The effects on operating temperature, secondary fluid, and tank capacity. Results showed that, For the effects on the operating temperature, the maximum efficiency of electricity generation, heat recovery efficiency, and combined heat and power efficiency are up to 32%, 43%, and 67%, For the effects on operation secondary fluid flow, the maximum efficiency of electricity generation, heat recovery efficiency, and combined heat and power efficiency are up to 31%, 59%, and 66%,For the effects on the operation tank capacity, the maximum efficiency of electricity generation, heat recovery efficiency, and combined heat and power efficiency are up to 31%, 49%, and 65% Respectively.
