HEAT PUMP ALL-IN-ONE FUEL CELL SYSTEM

摘要

PURPOSE: A fuel cell system integrated with heat pump is provided to counteract fluctuation of cooling or heating load without causing fluctuation of electric load. CONSTITUTION: A fuel cell system integrated with heat pump comprises a fuel cell part, a heat pump part, and a variable area type turbocharger (301). The fuel cell part generates electricity through electrochemical reaction and produces high temperature cathode off gas. The heat pump part includes an evaporator (302), a compressor (301B), a vaporizer with an expansion valve (304). The variable area type turbocharger connects the fuel cell part with the heat pump part. The variable area type turbocharger conveys the cathode off gas to a heat exchanger of the fuel cell part, generating driving force with the cathode off gas, and controls with the driving force the pressure and velocity of refrigerant circulating inside the heat pump part.
