Abstract With the increasingly serious environmental pollution, high efficiency, clean, no pollution and other advantages of fuel cell gradually began to replace fossil fuels become energy sector in the "favorite"。 In addition, in recent years, with the continuous development of micro computer and semiconductor power electronic components and technology, the great progress in variable frequency speed control technology in reducing harmonics and improve the efficiency, of electric propulsion technology has been widely applied in the ship up to the great help。 The continuous improvement of people's living standard, also contributed to the yacht tourism industry has broad market prospects。 Therefore, in the fuel cell electric propulsion system of the yacht design and research, in environmental protection, technology And economic development are  of  great significance。

Method, studied the present situation from the domestic and foreign fuel cell electric propulsion yacht, fuel cell types and working principle of electric power propulsion system composition, the classification and characteristics of combined with the ship propulsion system and ship matching principle to a small waterplane area catamaran yacht as an example, according to the work principle and the corresponding propulsion system, acceleration performance, endurance characteristics of propulsion motor of selection, and the comparison and demonstration of fuel cell selection and characteristics analysis and calculation of the fuel battery is rated efficiency, stack the actual efficiency and to meet the life requirements of the required fuel quality, draw out of the fuel cell Schematic diagram and schematic of the apparatus。 Combined with the chart analysis of the motor of the electric drive characteristics (including mechanical characteristic curve, starting, speed), according to the motor nameplate parameters are computed and plotted out the inherent motor mechanical characteristic curve, calculated starting segments required on the resistance of the resistance。

Keywords:Yacht; electric propulsion system; fuel cell; electric drive
