Description

technical field [0001] This field belongs to the field of energy saving and emission reduction of ship clean energy fuel cell technology, and more specifically relates to a high-efficiency zero-emission marine multi-fuel solid oxide fuel cell combined cooling, heating and power unit, and its use method. Background technique [0002] Traditional marine generator sets are mainly internal combustion engines (such as diesel engines, gas turbines, etc.), which have inherent shortcomings such as low power generation efficiency, heavy pollution, cumbersome maintenance, and poor fuel economy. Emissions, clean fuel, and intelligence" construction requirements, urgently need to develop new high-efficiency, quiet, and clean power generation technologies for ships. [0003] Solid Oxide Fuel Cell (SOFC) is a power generation device that directly converts the chemical energy stored in the fuel into electrical energy through an electrochemical reaction. It has wide fuel adaptability (hydro...

AI Technical Summary

Problems solved by technology

However, because proton exchange membrane fuel cells can only use high-purity hydrogen, there are problems such as high cost and poor safety in hydrogen production, storage, and transportation; if hydrocarbon fuels such as methanol and natural gas are used, the power generation efficiency of proton exchange membrane fuel cells Only 35-40%, and the utilization of waste heat is low, resulting in poor economy and safety needs to be improved
