摘要

本研究將針對一太陽能氫氧燃料電池之系統特性探討，此系統乃結合一太陽能電池，水電解器及氫氧燃料電池之環保產電系統。首先將對個別子系統做基本性能特性的測試，再對其整合特性做深入探討。其中太陽能電池部分探討其電流與電壓之關係、最大產電功率、太陽能半導體之特性等，水電解器部分探討如何測定亞佛加厥常數、水電解器電流與電壓之關係、水電解器之法拉第效率等，氫氧燃料電池部分探討其電流與電壓之關係、氫氧燃料電池之能源效率、法拉第第一定律之驗證等，最後為整合效率之特性。實驗使用150瓦之鹵素燈具來模擬太陽光，太陽能電池吸收鹵素燈具之光熱轉換為電能來驅動電解器電解水，電解水後產生氫氣和氧氣送到氫氧燃料電池產生電能。整合實驗中以改變內電阻來測試不同負載下之能源效率。藉此可對太陽能氫氧燃料電池之基本特性做有系統地探討。

This study investigates the characteristics of a solar hydrogen fuel cell system, combined with a solar cell, water electrolysis and hydrogen fuel cell system for environmental electricity generation. First, the basic performance characteristics for the individual subsystems are tested. Then, the overall efficiency of the integrated system is discussed in depth. For the solar battery, the relationship of current and voltage, the maximum production of electric power, and solar semiconductor characteristics are tested. For the water electrolysis, determination of Avogadro constant, relationship between water electrolysis current and voltage, and its Faraday efficiency are experimented. As for the hydrogen fuel cell, the relationship between current and voltage, the energy efficiency, the verification of the Faraday first law, and the integrated performance characteristics are examined. Experiments use a halogen lamp of 150 watts to simulate sunlight. Solar cells absorb the light and heat from the halogen lamp and convert it to electric energy used to operate the electrolysis of water. The electrolysis of water produces hydrogen and oxygen which is supplied to the hydrogen fuel cell to produce electricity. An experiment for an integrated system is set up to test the energy efficiency under different load by changing the electric resistance. Hence, a systematic test experiment for a solar hydrogen fuel cell system is achieved to explore the basic characteristics of the solar hydrogen fuel cell.
