TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The hydrogen purification device is a membrane separation device, which is a porous ceramic surface vacuum plated palladium silver alloy, where the film layer has palladium content of 75-78% and silver content of 22-25%. The reformer comprises a starting device comprising a cup base mounted with a raw material input pipe, a heating gasification pipe, an ignition device and a temperature detection device. The raw material input pipe inputs methanol and water raw material. The input pipe is connected to the gasification pipe. The methanol and water are allowed to enter into heating gasification pipe via raw material input pipe. The end of the heating gasification pipe is positioned to corresponding end of the ignition device and heating gasification pipeline, used for heating a gasification pipe and methanol and water raw material for ignition. The methanol and water raw material are subjected to ignition combustion, where the heat of combustion is used to heat the gasification pipe, where the heat of methanol and water heated gasification pipe increases combustion intensity so as to heat the reformer. The temperature detect device is used for detecting the temperature near the heating gasification pipe. A part of reformer prepares hydrogen gas and/or residual gas is combusted to maintain the reformer. The upper part of the cup base comprises an installation part, liquid storage part set on the installation part, a raw material input pipe, a heating gasification pipe, an ignition device and a temperature detection device. The temperature detection device is set on the cup base of the installation part. The liquid storage unit can accommodate the heating gasification pipe. The end of the export has methanol and water raw material. The top of the liquid storage unit has a liquid splash cover. The heating gasification pipe orderly comprises a straight pipe section, spiral pipe section and arc pipe section. The methanol and water raw material passes through the pipe section rising to the highest point. The spiral pipe section descends in a manner. The outlet of the arched pipe section of the cup base bottom side is mounted with air intake cover plate. The air intake cover plate is an air channel. The outer air passes through the air channel then into the reformer. An electromagnetic valve is set on the raw material input pipe so as to control the opening or closing of the raw material input pipe. The fuel cell vehicle also comprises an alternating current (AC)/direct current (DC) converter and buffer storage battery. The alternating direct current converter is connected with a fuel battery and an electric current input terminal, used for a fuel cell of a direct current electric output by DC/DC voltage transformation or DC/AC transformation, where the buffer storage battery is connected with AC/DC converter. The buffer storage battery supply power to the motor vehicle. A compensation vaporizing device is set between the heat exchanger and the reformer. The compensation vaporization device is provided with an electric heater. The compensation vaporizing device enables the supply of methanol and water vaporization vapor for power generation in an electric.
