METHOD AND INSTALLATION FOR MANUFACTURING HIGH- TEMPERATURE FUEL CELL

摘要

FIELD: single-process manufacture of solid-oxide fuel cells. SUBSTANCE: proposed method includes manufacture of solid-oxide high-temperature fuel cells by pyrolysis of organometallic complexes based on 2-ethyl hexane acid. Functional layers of fuel cell are applied by rolling precursor organometallic complexes of each layer onto fuel-element blank which is heated to pyrolysis temperature of respective precursor. Blank surface heating provides for evaporation of precursor organic component when liquid precursor comes in contact with blank, this being accompanied by formation of oxide film of respective functional layer. Blank surface temperature is varied in the course of layer production between 240 and 600 C depending on layer being produced. Installation implementing proposed method has rotating device for blank cathode made of strontium lanthanum manganite and device for applying precursor onto cathode. Layers are applied by means of roller directly contacting fuel cell blank. Layers can be applied to fuel cell blank surface both over cathode generatrix and over helical line. All functional layers of fuel cell are applied on mentioned installation; proposed method and device may be likewise found useful for applying functional layers on anode used as fuel cell blank. EFFECT: enhanced safety and reduced cost of method; simplified design and enhanced reliability of installation. 14 cl, 12 dwg
