1. A fuel cell system comprising:
- a fuel cell;
a secondary battery which is charged by the fuel cell;
a charge amount information detector arranged to detect charge amount information regarding an amount of charge in the secondary battery;
an electric current information detector arranged to detect electric current information regarding an electric current flowing in the secondary battery;
an estimation unit arranged to estimate a charging time for the amount of charge in the secondary battery to reach a target value, based on a result of detection by the charge amount information detector and a result of detection by the electric current information detector; and
a notification unit arranged to notify a result of estimation by the estimation unit.

Abstract
A motorbike is mounted with a fuel cell system which includes a cell stack, a secondary battery which is charged by the cell stack and a controller which has a CPU. After receiving an operation stop command which is issued from a main switch, the CPU estimates a charging time for a charge rate of the secondary battery to attain a target value, based on a voltage of the secondary battery and a charge current which are detected based on detection signals from a voltage detection circuit and an electric current detection circuit, as well as based on a charging time estimation table stored in a memory. The charging time estimated by the CPU is displayed in a display.
