Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0027] Such as figure 1 Shown is a block diagram of the system connection structure proposed by the present invention for suppressing the inrush current control method of methanol reforming hydrogen fuel cell grid-connected self-starting. The main circuit of the fuel cell stack is connected in series by the power grid, grid-connected inverter, DC / DC converter, and fuel cell stack, which mainly realizes the function of fuel cell grid-connected power generation; the auxiliary power supply circuit of the temperature control circulation system is composed of the starting power supply, DC / A DC converter, a heating body and an electric pump are connected in parallel, and are mainly use...
