Fuel cell system, exhaust purification method using fuel cell, and modification method of fuel cell device

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell system capable of purifying pollutants while generating electric power. SOLUTION: A fuel cell system 2 has a polluted exhaust line 6 for supplying a polluted exhaust containing a pollutant discharged from a facility 4, and a reaction heat of the fuel cell 14 for the polluted exhaust supplied from the polluted exhaust line 6. The polluted exhaust purifying unit 50 for purifying using the above is provided. The pollutants include substances that affect living organisms, such as bacteria, viruses or odor-causing substances. Facility 4 is a facility where the pollutant is brought in, a facility where the pollutant grows or a facility where the pollutant is created, or a laboratory, factory or isolation facility that handles the pollutant. The contaminated exhaust purification unit 50 is a power generation unit 36 of the fuel cell 14, and the contaminated exhaust line 6 supplies contaminated exhaust to the air electrode 38 of the power generation unit 36.
