Fuel cell system

Abstract

A fuel cell unit system is disclosed, which is provided in a multi-home energy supplying system, wherein the multi-home energy supplying system includes the plurality of fuel cell unit system provided to respective houses, and one common-use reforming unit to supply hydrogen to the plurality of fuel cell unit system, the fuel cell unit systems (40) comprising a stack unit (300) which generates electricity by an electrochemical reaction between supplied air and the hydrogen supplied from the common-use reforming unit (10); an air supplying unit (100) which supplies the air to the stack unit; an integral heat exchange unit (500) which cools the stack unit by recovering the heat from the stack unit, and stores the recovered heat; a hot-water supplying unit (200) which receives the heat stored in the integral heat exchange unit, and provides heat and hot water; an auxiliary heat supplying unit (400) which generates the heat by receiving the air supplied from the air supplying unit, and the hydrogen directly supplied from the common-use reforming unit or discharged from the stack unit after the electrochemical reaction, and supplies the generated heat to the hot-water supplying unit; and an electric output unit (600) which converts the electricity generated in the stack unit into a utility power, and supplies the produced utility power to the respective houses.

Description

technical field [0001] The present invention relates to a multi-dwelling energy supply system having fuel cell unit systems installed in each dwelling and a common reforming unit for supplying hydrogen to the fuel cell unit systems, more particularly , relates to a fuel cell unit system which can minimize the space occupied in each dwelling house and which can stably supply electric power and thermal energy to each dwelling house in all seasons. Background technique [0002] Recently, fuel oil is widely used as an energy source. However, fuel oil can cause environmental pollution. With the development of industry and the explosive growth of the number of cars, the price of oil is rising rapidly, and the fuel reserves are being depleted. For this reason, research on new energy sources that can replace fuel oil is required. In response to research on new energy sources, fuel cells have been developed. [0003] A fuel cell is an energy conversion device that converts chemic...

Problems solved by technology

If the size of the residential fuel cell system is large, the living space of each dwelling will be relatively reduced due to the large footprint of the residential fuel cell system, thus causing discomfort to the members of the house
