PROBLEM TO BE SOLVED: To supply hydrogen produced by decomposition of hydrogen resources such as ammonia, and to utilize an exhaust gas from a fuel cell for preventing hazardous substance releasing by. SOLUTION: An hydrogen producing apparatus is composed of a decomposer 2 in which the hydrogen resources are decomposed to nitrogen and hydrogen and to supply them to the fuel cell, a combustor 3 to combust the exhaust gas from the fuel cell 4 by a catalytic reaction, air feeding means 5 to feed combustion air to the combustor 3, an oxygen sensor 34 to measure oxygen concentration in the exhaust gas from the combustor 3 and a controller 6 to control the air feeding means 5. As the hazardous substance such as ammonia in the exhaust gas from the fuel cell is combusted and removed in the combustor 3, the releasing of the hazardous substances can be prevented. When heat from the combustor 3 is fed to the decomposer 2, energy efficiency is improved because a heat source to heat the decomposer 2 is not required. |
