A technique that is usable with a fuel cell stack includes coupling the fuel cell stack to a load, monitoring a power that is consumed by the load and determining if the power is increasing or decreasing. If the output power is increasing, a first control technique is used to control a fuel flow to the fuel cell stack, and if the output power is decreasing, a second control technique that is different from the first control technique is used to control the fuel flow to the stack.

A technique that is usable with a fuel cell stack includes coupling the fuel cell stack to a load, monitoring a power that is consumed by the load and determining if the power is increasing or decreasing. If the output power is increasing, a first control technique is used to control a fuel flow to the fuel cell stack, and if the output power is decreasing, a second control technique that is different from the first control technique is used to control the fuel flow to the stack. ent number of discharge pulses stored in the database, generates output data indicating result of the prediction, and transmits the output data to the output terminal. 5. The laser device management system according to claim 1, wherein, when the laser device is a gas laser device for performing laser oscillation of a gas laser, the laser control apparatus acquires as the state data indicating the operational status of the gas laser device including the number of discharge pulses that affects lifetime of components used in the gas laser device, and transmits the state data to the server device, and the generation means of the server predicts the lifetime of the components based on the state data stored in the database, generates output data indicating result of the prediction, and transmits the output data to the output terminal. 6. The laser device management system according to claim 1, wherein the event comprises a passage of a fixed amount of time. 7.
