Recent Development Aspects of Metal Supported Thin-Film SOFC

Abstract

The metal supported solid oxide fuel cell (MSC) technology has attained high interest for the electrical power supply of vehicles by auxiliary power units (APUs) which operate independently from the main engine. Its main advantages compared to other SOFC technologies are higher mechanical stability and better thermal and redox behaviour, which are indispensible for mobile applications. For many years, Plansee has developed and fabricated porous metallic substrates, interconnector plates and protective coatings for various types of SOFCs which are used in mobile as well as in stationary applications. Plansee has recently developed technologies for the production of MSCs in close cooperation with various partners from science and industry. This paper presents results of this development.

Synthesis of NiAI intermetallic compound as a metal support for solid oxide fuel cells

“…Металл тіреуіші негізіндегі қатты оксидті отын элементтері Ni, FeNi, NiCrAlY және тот баспайтын болаттан жасалған ферритті металдарды қоса алғанда әртүрлі металл құрамы бар субстратта дайындалды [1]. Көптеген құрастырушылар құрамында 10,5-26% Cr бар тот баспайтын болатты құнының төмендігі, жемірілуге төзімділігі және жылулық кеңею коэффициенттері қатты электролит материалдарына жақын болғандықтан металл тіреуіші ретінде ұсынады [2,3]. Ферритті тот баспайтын болаттағы хром мөлшері 10,5% асқан кезде, ме-талл тіреуішті оның әрі тотығуынан қорғау үшін жұқа және өткізгіш хром қабыршақтары пайда болады.…”

Degradation Mechanisms of Metal-Supported Solid Oxide Cells and Countermeasures: A Review

“…Moreover, metal-supported cells (MSCs) show much better stability in the rapid thermal and redox cycling than ASCs as the metals’ excellent ductility and high thermal conductivity, which can significantly mitigate the thermally induced stress during the operation [ 6 , 23 , 24 , 25 , 26 ]. These excellent physical properties allow the cell stack with metal-supported SOFCs more compact to get higher power density and also to be with superior fast-startup capability [ 27 , 28 , 29 , 30 , 31 ].…”

Dual-Phase Cathodes for Metal-Supported Solid Oxide Fuel Cells: Processing, Performance, Durability

“…11,13 Since 2008, Plansee SE (PSE, Reutte, Austria) has developed an MSC concept based on its ITM (intermediate temperature metal) oxide-dispersion-strengthened ferritic steel support in close cooperation with Forschungszentrum Jülich GmbH (Jülich, Germany). [14][15][16][17][18] While the fabrication of anode, electrolyte, and diffusion barrier layers (DBLs) can be adapted to applications on the metal substrate, a separate cathode sintering step has not yet been implemented in the state-of-the-art process. This is due to the contradicting requirements of the metal substrate and the cathode with regard to the sintering atmosphere.…”
