| Abstract | In 1995 a fuel cell program was established at Forschungszentrum Jülich (FZJ) to combine various and independently existing activities on generic fuel cell research. As of this year, the materials development as well as the component manufacturing was focused on anode-supported cells. This contribution reviews the investigations on many materials and the fabrication processes applied for anode substrates, anodes, electrolytes and cathodes. Continuous effort on each of the components resulted in a steady progress in quality, size and performance of the solid oxide fuel cells (SOFCs). The electrochemical performance of anode-supported cells (ASC) with “conventional” electroceramic materials like lanthanum manganite as cathode, yttria-stabilized zirconia (YSZ) as electrolyte and a NiO/YSZ composite as anode and anode substrate was improved from about 0.15 W/cm$^{2}$ at 800$^{∘}$C to 1.2 W/cm$^{2}$ by optimization of processing and microstructure. Considering new perovskite materials like lanthanum cobaltite/ferrite as cathode, a power density of 1.4–1.7 W/cm$^{2}$ has been obtained. In addition to these strongly focused activities on ASC, FZJ has carried out R + D projects together with industrial companies for the planar and tubular electrolyte-supported cell systems (Siemens, Dornier).This review, however, also discusses efforts that were less successful for anode-supported SOFCs. As examples are mentioned here the lanthanum gallates as electrolyte materials or low-cost NiO/Al$_{2}$O$_{3}$ substrates, which are not dimensionally stable in fuel gas atmosphere. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
