The present invention relates to an electric propulsion system and a ship including the same. According to the present invention, the electric propulsion system equipped with a power generation engine and a fuel cell for consuming a gas fuel of a liquefied gas storage tank mounted on a ship to produce electricity for propulsion of the ship comprises: an economizer which heats fresh water using exhaust gas discharged from the fuel cell; and a boiler which converts the fresh water heated in the economizer into steam using exhaust gas discharged from the power generation engine. The economizer and the boiler are provided in series based on the flow of the fresh water.

    본 발명은 전기추진 시스템 및 이를 포함하는 선박에 관한 것으로서, 선박에 탑재된 액화가스 저장탱크의 가스연료를 소비하여 상기 선박의 추진을 위한 전기를 생산하는 발전엔진과 연료전지를 구비한 전기추진 시스템으로서, 상기 연료전지에서 배출되는 배기를 이용하여 청수를 가열하는 이코노마이저; 및 상기 이코노마이저에서 가열된 청수를 상기 발전엔진에서 배출되는 배기를 이용하여 스팀으로 변화시키는 보일러를 포함하며, 상기 이코노마이저와 상기 보일러는, 청수의 흐름을 기준으로 직렬로 마련되는 것을 특징으로 한다.
