It has been difficult to reduce a waste of energy in a fuel cell power generating
process when, for example, a temporary rise or drop of a power load occurs. A fuel
cell power generation system includes: load detection means of detecting power
requested by a load; and output control means of accumulating a time at which a
detected power requested by the load is equal to or larger than a predetermined
value when a fuel cell body does not generate power to be supplied to the load,
and allowing the fuel cell body to start generating power to be supplied to the
load according to a predetermined rule based on an accumulation result.
