Closed space fuel cell power generation system based on reforming hydrogen production

Abstract

The invention discloses a closed space fuel cell power generation system based on diesel reforming hydrogen production. The closed space fuel cell power generation system comprises a diesel storage tank, a diesel pump, a hydrogen peroxide storage tank, a hydrogen peroxide pump, a diesel preheater, a diesel reformer, a hydrogen peroxide preheater, a hydrogen peroxide reactor, a diesel desulfurization reactor, a water segregator, a fuel cell module, a collecting water tank and the like. Hydrogen-rich reaction gas is obtained by reforming and desulfurizing diesel oil, oxygen is obtained by the heating and catalytic decomposition of hydrogen peroxide, and electric energy and heat energy are generated by the chemical reaction of the hydrogen-rich reaction gas and the oxygen in the fuel cell module, so that the urgent demand of an anoxic or hypoxic closed space on the electric energy can be met; and the system effectively overcomes the defects of low energy density, poor replenishment convenience, complex system composition, high use cost and the like in the existing technical scheme, and has wide application prospects and potential application values in the fields of aviation, aerospace, underwater, deep ground and other closed spaces.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a fuel cell power generation system in a closed space based on reforming hydrogen production. Background technique [0002] Confined space is a relatively common environmental condition in aviation, aerospace, underwater and deep ground applications. In a confined space, due to the scarcity of oxygen, traditional power devices such as diesel engines and gasoline engines cannot be used normally, and batteries cannot meet the application requirements due to low specific energy and safety. High-efficiency power generation devices used. Due to the advantages of high energy conversion efficiency, high energy density, low oxygen consumption rate, and low vibration and noise, fuel cells are recognized as the most promising power generation technology for confined spaces. [0003] At present, the existing fuel cell systems in confined spaces mostly use pure hydrogen and ...
