Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] refer to figure 1As shown, the present invention discloses an online high-purity hydrogen preparation system for fuel cells, including a methanol tank 8 and a raw material tank 1 and a catalytic burner 7 connected to the methanol tank 8 through a methanol metering pump 9, and methanol flows through the methanol The metering pump 9 is divided into two branches and transported to the raw material box 1 and the catalytic burner 7 respectively, and an on-off valve 9.2 and a mass flow controller 9.1 are sequentially connected between the methanol metering pump 9 and the raw material box 1. A regulating valve 9.3 is connected between the methanol metering pump 9 and the catalytic burner 7, and the flow of methanol is controlled and regulated by the methanol metering pump 9, mass flow controller 9.1, on-off valve 9.2 and regulating valve 9.3. There is a fuel...
