HIGH EFFICIENT RESIDENTIAL POWER GENERATION SYSTEM BY USING HYDROGEN CATALYTIC BURNER AND HEAT FROM PEMFC

摘要

A high efficient integrated residential power generation system using the waste heat of a PEMFC(Proton Exchange Membrane Fuel Cell) and a hydrogen catalytic burner is provided to save energy by collecting heat energy of water and exhaust air generated in a PEMFC stack and collecting the heat energy of cooling water flowed out from a cooling system of the PEMFC stack and storing the heat energy in a heat storing device. A high efficient integrated residential power generation system using the waste heat of a PEMFC and a hydrogen catalytic burner maximizes energy efficiency by using waste heat generated in a PEMFC stack and a hydrogen catalytic burner. Hydrogen gas remaining in the PEMFC stack is used in the hydrogen catalytic burner and the efficiency is improved. Hydrogen and air supplied to the PEMFC stack are heated by electric heaters(H1,H2) and front and rear temperature sensors. The PEMFC stack, the hydrogen catalytic burner, a heat storing device, and a peripheral system are inserted into one case. The temperature of hot water and heating water is adjusted through heat exchange between water and gas burnt by using the hydrogen catalytic burner and doors(D1,D2,D3,D4) blocking or controlling the flow of the burnt gas.
