Abstract

The invention discloses a battery system, which comprises an electrolysis unit, a fuel cell unit, a first heat exchange unit, a heat consumer unit, wherein the electrolysis unit is used for generating hydrogen and oxygen; water vapor is mixed into the hydrogen and the oxygen; the fuel cell unit is connected with the electrolysis unit and generates heat energy by use of reaction of air and the hydrogen generated by the electrolysis unit; the hydrogen and/or the oxygen generated by the electrolysis unit absorbs heat in the hydrogen and/or the oxygen by use of the first heat exchange unit and liquefies the water vapor into cooling water through the first heat exchange unit; and the heat consumer unit is connected with the first heat exchange unit to recycle the heat generated by the first heat exchange unit. Through the battery system, the problem of low energy utilization efficiency of a proton exchange membrane fuel cell system in a related technology is solved.

Description

technical field [0001] The present invention relates to the field of batteries, in particular to a battery system. Background technique [0002] The proton exchange membrane fuel cell system requires hydrogen as the reaction raw material. At present, high-pressure hydrogen storage is generally used. However, the sustainability of its discharge is limited by the scale of the hydrogen storage device, and hydrogen fuel needs to be replenished regularly. There are also some other methods for providing hydrogen fuel in the prior art: For example, method one uses a reformer to convert hydrogen-rich fuel into hydrogen and provide it to the fuel cell as fuel, but there are the following problems, the reformer needs to consume extra power and cause Heat and energy loss, the reformer needs to desulfurize and remove carbon monoxide, which makes its system extremely complex and expensive; method 2 uses the mains as the energy source to produce hydrogen through the electrolytic stack to...
