1. An output integration system for a plurality of fuel cell engines, the output integration system configured to integrate outputs from the plurality of fuel cell engines, the output integration system comprising one or more processors that are provided at an interior or an exterior of the fuel cell engines and execute computer-executable instructions stored in a memory,
wherein each of the fuel cell engines comprises:
a fuel cell stack;
a fuel tank configured to store a fuel gas supplied to the fuel cell stack; and
a load configured to be supplied with electrical power from the fuel cell stack, and to generate a driving force, and
wherein the one or more processors execute the computer-executable instructions to cause the output integration system to:
acquire a difference in a residual amount of fuel in the fuel tanks between the plurality of fuel cell engines;
adjust a required load output, which is an electrical power consumption amount of each of the loads, so as to reduce the difference; and
in a case that each of the fuel cell engines includes a plurality of the fuel cell stacks, and each of the fuel tanks that supplies fuel to each of the fuel cell stacks is constituted by a plurality of fuel tanks, acquire a difference in the residual amount of fuel between the plurality of the fuel tanks that supply fuel to each of the fuel cell stacks, and adjust the electrical power output of each of the fuel cell stacks within each of the fuel cell engines, so as to reduce the difference.
