Description

technical field [0001] The invention relates to a multi-fuel self-adaptive fuel cell integration system and integration method, which are mainly used in distributed energy supply places such as commercial centers, hospitals, airports and data centers, and areas rich in biomass resources as places for distributed energy . Background technique [0002] Gas distributed energy refers to the use of natural gas as the main fuel to realize the cascade utilization of energy through combined cooling, heating and electricity. The comprehensive energy utilization efficiency is above 70%, and the modern energy supply mode that realizes energy supply at the nearest load center , is an important way of efficient utilization of natural gas. The solid oxide fuel cell (SOFC for short) is an all-solid-state chemical power generation device that directly converts the chemical energy stored in fuel and oxidant into electrical energy in an efficient and environmentally friendly manner at medium...
