質子交換膜燃料電池效率高，無污染。為目前國內積極研發之電源供應裝
置。為使質子交換膜燃料電池可正常運作，須配合其他元件架構一燃料電池系統
以確保氣體之正常供應。本文使用HPOWER-PS250 為燃料電池本體來架構完整電
池系統。為達成燃料電池之系統整合，需要一完整之模型正確的描述燃料電池之
性能與特性。本研究根據文獻中之燃料電池靜態模型、氣體壓力動態模型及等效
電路模型，再整合此HPOWER 燃料電池特有之各部元件，發展成一完整之動態模
型來描述該質子交換膜燃料電池系統之性能表現。最後再利用一系列之實驗來驗
證所發展之系統模型，結果顯示此模型可正確描述系統性能。而其動態響應將對
系統性能造成重大影響。

Proton exchange membrane fuel cell (PEMFC) is high-efficient and
pollution-free. Currently it is an actively researched alternative power supply
device nationwide. For the PEMFC to operate normally, the stack must be
equipped with supporting components that maintain the required fuel supply
and operating conditions, thus forming an integrated fuel cell system. In this
study, an HPOWER-PS250 fuel cell system is the basis of the structure and is
to be analyzed and integrated. For the purpose of system integration, a model
that can accurately describe the characteristics and behavior of this fuel cell
system is needed. Therefore, in this study an integrated fuel cell system model
is developed. The model is established based on the unique components of
this fuel cell stack, and subsystem models that have been reported in the
literature, including the static fuel cell model, the fluid dynamics model of the manifold and the flow channel, and the equivalent circuit model for the stack output. Finally, a series of experiments are conducted to verify the developed fuel cell system model. The results show that this model can accurately describe the characteristics and behavior of this fuel cell system. It is found that the dynamic response have significant effect to on the performance of the fuel cell system.
