質子交換膜燃料電池應用於船舶輔助電力的模擬

Simulation of PEM Fuel Cells for Applications in Auxiliary Power in Ships

本文以燃料電池之數學模型來模擬質子交換膜燃料電池之輸出電壓與電流，藉以探討其作為船舶輔助電力供應之可行性。文中利用直流／交流電力轉換器將燃料電池之直流電力轉換為交流電力，再經變壓器升壓至120伏特，以提供以船舶所需之負載，並探討負載對燃料電池發電之特性。 The mathematical model of proton exchange membrane (PEM) fuel cells is used to simulate the output voltages and currents of PEM fuel cells in this paper. The purpose of this paper is to study the feasibility of using the output voltages and currents of PEM fuel cells as auxiliary power in ships. Moreover, this paper uses a dc-to-ac power converter to convert the dc voltage to ac voltage and step up the ac voltage to 120 volts through a transformer for supplying to the loads of a ship. Meanwhile, the effects of loads changes on the power generation of PEM fuel cells are investigated.
