Solid oxide fuel cell has become one of the interest in the sustainable energy field. In order to improve the efficiency of a solid oxide fuel cell (SOFC), the interconnect must be coated with a protective coating of (MnCO)3O4 spinel coated stainless steel. Commercial manganese cobalt (MnCO)3O4 was used as a protective coating on ferritic stainless steel in this study using the electrophoretic deposition (EPD) coating technique. This article examines the impact of voltage deposition towards morphological characteristics. The goals of these studies are to find the best interconnect coating parameter while experimenting with voltage deposition. The spinel coated interconnect (MnCO)3O4 was studied using Elemental Energy Dispersive X-ray Spectroscopy (EDS). The surface morphology and coating thickness are examined using a Scanning Electron Microscope (SEM). X-ray diffraction (XRD) is used to determine the phase of the spinel coated interconnect. The EPD coating technique for (MnCO)3O4 spinel coated interconnect is carried out in an aqueous suspension with 30V and 40V with coating durations of 20s, 30s, 40s, 50s, and 60s. By observing the deposition morphology and thickness coating at 30V and 40V, the best covering parameter for interconnect is 30V, 40s which fulfil the interconnect requirement.

In this study, ceramic foams were produced using starch consolidation casting method. This research focused on the preparation of alumina-based ceramic foam by using corn starch as a pore-forming agent. Preparation of alumina based ceramic foam is studied to observe the effect of the addition of corn starch on its physical, mechanical and morphological properties. The composition of the suspension used included 64–58 wt.% alumina, 55 wt.% deionised water and other materials, such as silica and polyethylene glycol (PEG), were used as additive and dispersing agent respectively. Corn starch was added at 4, 6, 8 and 10 wt.%. The samples were preheated for gelation and coagulation processes, then dried and sintered at 1250 °C for 2 h. The ceramic foam gave a linear shrinkage from 1.07% to 3.39%. The obtained flexural strength was between 0.594 and 1.996 MPa. The average total porosity ranged from 54.05% to 70.70%. This study found that the suitable amount of corn starch in alumina foam is 4 wt.% because the resulting porosity values and flexural strength are appropriate for ceramic foams.

A fuel cell is an electrochemical device that provides efficient power generation. Solid fuel oxide cell (SOFC) is an electrochemical device that generates electrical energy and heat from the gaseous state of fuel using an oxidant. SOFC is a highly efficient and environmentally friendly power generation technology that generates electrical energy from hydrogen gas, natural gas and other renewable fuel. The implementation of SOFCs is still facing challenges because their performance needs to be improved. Constructing cells with solid material alone is difficult because good electrical contacts between the components must be maintained. The concept of a dual composite cathode is important for the development of SOFC single cells. Introducing dual composite cathode can create an ideal cathode microstructure that can improve phase contiguity and interfacial coherence. This paper reviews the behaviour of a perovskite-type oxide-based dual composite cathode of SOFC for the selection of suitable materials and the preparation of a dual composite cathode.
