碩士 / 明道大學 / 材料暨系統工程研究所 / 95 / Fuel cell propulsion system is the next step of a warship service power system development for the Office of Naval Research. In the propulsion system, electric power generated by fuel cells is transferred to a motor drive, where the voltage and frequency of the electrical energy are modified to operate the propulsion motor at a desired speed. The propulsion motor converts the electrical energy delivered by the motor controller into mechanical energy to rotate the propeller shaft. The advantages of the fuel cell propulsion system, compared to traditional propulsion systems, are high power density, more sensitive control, greater flexibility in the internal arrangement of machinery spaces, a higher modularity potential, the ability to allocate power at will among propulsion, reduction of power system emissions, stealth enhancement, and reduced logistics dependency.
The purpose of this project is to development the fuel cell propulsion system for navy ships. The pivot technique of the propulsion system is a ship service fuel cell power generation module. The project will be assessed the effect of salt air on fuel cell operation, and qualified the fuel cell to shock and vibration standards. Besides, the demonstration module of the fuel cell propulsion system is set and stuies the performance in a test warship.
