1. A power management system comprising:
a plurality of power adjustment resources electrically connected to a power grid; and
a server that manages the plurality of power adjustment resources, wherein
the plurality of power adjustment resources include a plurality of fuel cell electric vehicles that each supplies electric power to the power grid,
the plurality of fuel cell electric vehicles each executes a refresh process that removes an oxide film formed on a platinum catalyst electrode of a fuel cell by causing the fuel cell to increase generated electric power to exceed prescribed electric power for a period of time of approximately several hundred milliseconds to several seconds, and
the server controls the plurality of fuel cell electric vehicles such that each of the plurality of fuel cell electric vehicles repeats the refresh process intermittently, and adjusts execution timings such that the refresh process is repeated without any overlap of the execution timings in the plurality of fuel cell electric vehicles.
