POWER OUTPUT DEVICE WITH FUEL CELL AND METHOD THEREFOR
First Claim
1. A power output device comprising:
- a fuel cell;
a calculation device that calculates a parameter corresponding to a maximum possible electric power from the fuel cell;
a determining device that compares the calculated parameter with a predetermined value and for determining a state of a power shortage of electric power; and
a notification device that provides notification of the power shortage when the state of power shortage is determined by the determining device, wherein the calculation device includes a cell characteristic detecting device that detects a characteristic of the fuel cell, and wherein the calculation device calculates the parameter on the basis of the characteristic of the fuel cell detected by the cell characteristic detecting device.

Abstract
An output limitation warning lamp is turned on when a possible output Qf of the fuel cell is less than a predetermined value L2. The output limitation warning lamp is provided at a combination meter in an instrument panel. The output limitation warning lamp is also turned on when a possible output Qb of the secondary battery is less than a predetermined value L3. Furthermore, the output limitation warning lamp is also turned on when an allowable drive output Qh, which is the sum of the possible output Qf of the fuel cell and the possible output Qb of the secondary battery, has been less than a required output Ed* calculated at a step before carrying out output limitation to more than a certain extent for longer than a predetermined length of time.
