Abstract

The invention discloses an energy supply method an energy supply system. The system comprises an electrolysis galvanic pile used for utilizing the electric energy to electrolyze water to produce an electrolysis gas, a fuel cell galvanic pile communicated with the electrolysis galvanic pile and used for outputting the electric energy according to a chemical reaction produced by the electrolysis gas, a heat exchanging device communicated with the electrolysis galvanic pile and / or fuel cell galvanic pile, and a heat supply device communicated with the heat exchanging device and used for outputting the heat energy through heat provided by the heat exchanging device, wherein when used for being communicated with the electrolysis galvanic pile, the heat exchanging device absorbs the heat produced in electrolysis of the electrolysis galvanic pile, and / or when used for being communicated with the fuel cell galvanic pile, the heat exchanging device absorbs the heat produced in the chemical reaction of the fuel cell galvanic pile. Through the method and the system, the problem of relatively low energy conversion efficiency of the energy supply system in the related technique is solved.

Description

technical field [0001] The present invention relates to the field of energy, in particular to an energy supply method and system. Background technique [0002] The combined heat and power system (referred to as the combined heat and power system) can provide heat and electricity to the community. The combined heat and power system can use a variety of energy sources, including the use of new energy, for example, through the combination of fuel cell stacks and electrolytic hydrogen production. The integrated heat and power cogeneration system can use new energy sources such as wind energy and solar energy to perform grid-connected peak regulation on the grid. The combined heat and power system using proton exchange membrane fuel cell stacks requires hydrogen to provide energy. Hydrogen is usually stored in the form of high-pressure hydrogen. The scale of the hydrogen storage device restricts the sustainability of the discharge, and hydrogen fuel needs to be regularly replenis...
