Study on improvement in efficiency of partial load driving of installing fuel cell network with water electrolysis operation

Abstract

The hydrogen and oxygen fuel pipes, electric power line and exhaust heat output line of fuel cell co-generations for individual houses are connected, and cooperation operation is carried out. The energy demand pattern of the individual house in Tokyo was introduced, and the analysis method aiming at minimization of the operation cost by the genetic algorithm was described. The fuel cell network system of an analysis example assumed connecting the fuel cell co-generation of five houses. Compared with the energy supply method of the conventional system, the amount curtailment of consumption of 9% of city gas estimated at the maximum by the energy supply of the fuel cell network system from the result of analysis. 2% of this is an effect when introducing water electrolysis operation by fuel cells, and using the method corresponding to partial load operation of fuel cell co-generation.
