Developing materials for SOFC applications is one of the key topics in energy research. The book focuses on manganite structured materials, such as doped lanthanum chromites and lanthanum manganites, which have interesting properties: thermal and chemical stability, mixed ionic and electrical conductivity, electrocatalytic activity, magnetocaloric property and colossal magnetoresistance (CMR). These materials have applications in solid oxide fuel cells, high temperature NOx sensors, hard disk read heads, magnetic sensors and magnetoresistive random access memories. For the first time, the charge density distributions have been studied in these materials as synthesized by high temperature solid state reaction. Charge density analysis is helpful in understanding the physical and chemical properties of materials and in developing optimized structures. The morphological, elemental, optical and magnetic properties of the materials have also been studied.

Fuel cells are expected to play a relevant role in the transition towards a sustainable-energy-driven world. Although this type of electrochemical system was discovered a long time ago, only in recent years has global energy awareness, together with newly developed materials and available technologies, made such key advances in relation to fuel cell potential and its deployment. It is now unquestionable that fuel cells are recognized, alongside their possibility to work in the reverse mode, as the hub of the new energy deal. Now the questions are, why are they not yet ready to be used, despite the strong economic support given from the society? What prevents them from being entered into the hydrogen energy scenario in which renewable sources will provide energy when it is not readily available? How much are researchers involved in this urgent step towards change? This book gives a clear answer, engaging with some of the open issues that explain the delay of fuel cell deployment and, at the same time, it opens a window that shows how wide and attractive the opportunities offered by this technology are. Papers collected here are not only specialist-oriented but also offer a clear landscape to curious readers and show how challenging the road to the future is.
