Solid oxide fuel cell stack allowing direct propane partial oxidation reforming for hydrogen production

Abstract

The invention relates to the technical field of cells, in particular to a solid oxide fuel cell stack allowing direct propane partial oxidation reforming for hydrogen production. The solid oxide fuelcell stack allowing direct propane partial oxidation reforming for hydrogen production comprises a columnar tube furnace, a wide-mouth microporous pipe, a catalyst unit, tubular solid oxide fuel cells, an oxygen inlet pipe, an air inlet pipe and an air outlet pipe, wherein the wide-mouth microporous pipe and the catalyst unit form a chamber for hydrogen production by deforming, a microporous segment and the tubular solid oxide fuel cells form an electrochemical reaction chamber, and the tubular solid oxide fuel cells enable oxygen in a cavity of the columnar tube furnace and hydrogen generatedthrough hydrogen production by deforming in the microporous segment to be subject to electrochemical conversion so as to generate a current. Through the solid oxide fuel cell stack allowing direct propane partial oxidation reforming for hydrogen production, the technical defects that current fuel cells are prone to carbon accumulation, consequently the cells fail, and the cells are damaged because anode tubes are prone to heat expansion are overcome.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a solid oxide fuel cell group for direct propane partial oxidation reforming to produce hydrogen. Background technique [0002] Today, with serious environmental pollution problems and increasingly depleted fossil fuels, hydrogen energy, as a new type of efficient and clean energy, is the general trend to replace chemical energy. Hydrogen energy will not produce any substances harmful to the environment during the entire energy conversion process. However, when hydrogen is used as a direct fuel energy, it faces safety problems such as easy leakage and flammability, as well as problems such as difficult transportation and storage. Moreover, hydrogen is a secondary energy source and cannot be obtained directly from nature. [0003] The solid oxide fuel cell is composed of two electrodes and a solid electrolyte between the electrodes. It is an all-solid-state electrochemical powe...

Problems solved by technology

If the hydrocarbon fuel is directly fed into the solid oxide fuel cell to produce hydrogen by oxidative reforming reaction, carbon deposits will easily occur and the battery will fail, and the thermal expansion of the anode tube will easily cause damage to the battery.
