因應全球節能減排趨勢和提倡獨立發電系統，各國致力發展潔淨次世代能源。氫能具有來源豐富、應用層面廣和低污染等優點，故可成為次世代綠色能源載體，目前產氫來源大多採用化石燃料為原料，此製程技術在未來而言將不適用，因而需發展潔淨製氫技術和獨立發電系統，本研究結合乙醇進料產氫設備與質子交換膜燃料電池發電系統，藉以熱力學第一、第二定律之「可用能分析法」，分析此發電系統之各組成子系統可用能損失和效率表現以及整體發電系統效率，藉由降低損失功提高整體系統效率，故可根據本研究結果來改善系統效率，以達到最佳化的發電效率
由熵分析，可以深入瞭解化學反應、熱傳和摩擦力這三種效應對熵增所造成的影響，以及熵增與產氫效率的關係。
可用能分析法設計出來的發電系統，再經由經濟分析(淨現值法，內部報酬率法，益本比法)，找出最適合投資的專案與地點。

In the last few years, energy crisis's production, causes regarding the new energy to seek is urgent, thus the fuel cell is born, enables the new energy to have the new direction. Moreover, the increasingly serious environmental issues, green energy development is also becoming increasingly important. This paper presents a hybrid power systems design combined with solar and hydrogen energy to supply the load demand. Ethanol is fed into a reformer reactor to generate hydrogen in order to achieve the goal of green energy. Hydrogen supply to the proton exchange membrane fuel cell and solar complement each other with day to supply the load demand. Finally, analyze the cost-benefit by using NPV (Net Present Value, NPV), benefit ratio (Benefit-Cost Ratio, B/C), analysis of indicators to assess the design of these hybrid power systems economic benefits.
Using the exergy analysis system, in the energy which the analysis system transforms, available with loss part, seeks causes the system to affect a more remarkable main variable. Therefore discovers system's best operating condition is necessary.
By using the entropy analysis, the impact of chemical reactions, heat transfer and friction on entropy generation and the relation between entropy generation and hydrogen-producing efficiency have been investigated.
