Abstract

The invention discloses a marine fuel cell combined heat and power system which comprises a fuel cell electric pile, a marine power grid, an expansion water tank, an air conditioning system, a hot water supply heat exchanger, a heating heat exchanger and a water-cooled board heat exchanger. The fuel cell electric pile is connected with the expansion water tank, the air conditioning system, the hotwater supply heat exchanger, the heating heat exchanger and the water-cooled board heat exchanger by cooling pipelines. The marine fuel cell combined heat and power system disclosed by the inventionsufficiently utilizes the characteristic that a water temperature and heat at an outlet of the fuel cell electric pile are high and can be utilized in a classified mode, and adopts a radiator installed inside a hull to supply heat to a cabin room and/or provide hot water required by the life; meanwhile, the system also sufficiently utilizes a natural low-temperature heat source function of seawater, does not require a heat dissipation fan and also has no parasitic power consumption; efficiency of the fuel cell system is improved; and meanwhile, for an abnormally high water temperature of the fuel cell system, which is caused by an abnormal working condition of the system, a cell cooler in an air conditioning system loop is adopted to carry out rapid cooling on the system.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a marine fuel cell combined heat and power system. Background technique [0002] A fuel cell is a clean power generating device that directly converts the chemical energy of fuel into direct current electrical energy. Its working principle is to convert the chemical energy of substances into electrical energy through electrochemical reactions, and the materials required for the fuel cell chemical reaction are continuously replenished from the outside. As long as the fuel is supplied, the energy will continuously output electrical energy and heat energy. [0003] Proton Exchange Membrane Fuel Cell (PEMFC) is an electrochemical power generation device that uses hydrogen as fuel and oxygen as oxidant. Due to the advantages of environmental friendliness and high energy conversion efficiency, it is widely used in automobiles. [0004] Proton exchange membrane fuel cel...
