In order to solve the problem of heat dissipation in the process of producing hydrogen from electrolytic water and generating electricity from fuel cells, an independent photohydrogen fuel cell thermoelectric combined supply system was designed according to the principle of water cooling heat dissipation between electrolytic cell and fuel cell. Based on this model, a control strategy was formulated to coordinate the output order and size of each module, which solved the inefficiency of electrolytic cell in low power operation zone. The capacity allocation model was established with the objective function of optimal comprehensive cost, and the optimal capacity allocation result of the system was obtained by using the particle swarm algorithm. The simulation results show that the overall cost of the configuration scheme proposed can be reduced by 2.2% compared with the traditional configuration scheme, and it can meet the same starting and ending states of the hydrogen storage tank and the heat storage tank during the operation cycle. The long-term energy supply effect of the system is excellent, which can provide a reference value for the capacity configuration of the current stand-alone photohydrogen fuel cell cogeneration system.
