Electric vehicle

Abstract

Abstract PURPOSE:To enable sufficient power supply from an auxiliary cell until output is produced fro a fuel cell, when an electric vehicle is started, by charging through the fuel cell until the auxiliary cell is charged over a predetermined level upon operation of a drive/stop switch. CONSTITUTION:Water in a water tank 6 and methanol in a methanol tank 9 are employed as reforming material in a mixer 8, then hydrogen and carbon diexide are produced through a methanol reforming unit 1. A fuel cell 2 produces electromotive force based on the hydrogen and oxygen in the air. Output therefrom is fed through a DC/DC converter 3 to a traveling DC motor 5a and a load/unload pump motor 5b, and it is also employed for charging of a lead battery 4. When a key switch 45 is turned ON, a controller 37 detects the charged condition of the lead battery through the voltage detecting section 41, a current sensor 42 and a temperature sensor 43, and operation of the fuel cell 2 is continued until the lead battery 4 is charged to a predetermined level.
