Abstract: A time zone when the operation pattern is obtained with a high learning convergence and a time zone when such an operation pattern cannot be obtained are set in advance. In the case where a significant difference develops between a target operation pattern and an actual load pattern, it is possible to accurately determine whether the operation is to be continued without changing the operation pattern or the operating conditions such as the hydrogen production amount should be changed in accordance with the actual load pattern. As a result, based on the scheduled operation with a predetermined operation pattern, the operation can be easily corrected in accordance with the complicated load change in home applications.

Abstract: A fuel-cell power system includes a fuel cell stacks, a power conversion unit for controlling and receiving the current from the fuel-cell stacks, a hydrogen production unit for supplying hydrogen to the fuel-cell stacks, and an operation unit for carrying out the operation with a simulated load connected for selected one of an arbitrary time and a predetermined time before the service operation of the fuel-cell power system, thereby the hydrogen production unit having the combustor for refluxing and combusting an anode off-gas is started in stable fashion at the same time as the system.

Abstract: The present invention relates to a plate-shaped catalyst unit for NOx reduction of exhaust gas, wherein molten metal is sprayed upon surfaces of a metal plate allowing the molten metal to accumulate thereon to form rough surfaces, and the rough surfaces thus obtained are deposited with a catalytic substance for NOx reduction of exhaust gas.The catalyst units thus obtained are each disposed in parallel with the gas flow, and generally arranged across the gas flow and at intervals in the catalytic reactor which is placed in an exhaust gas duct and used as an apparatus for nitrogen oxides (NOx) reduction of exhaust gas.
