the fuel cells are distinguished as generating of green allocable energy and are electrochemical devices of low environmental impact. porous nanocrystalline strontium-doped lanthanum manganite la0.8sr0.2mno3 (lsm) cathode materials were prepared by mechanochemical route in various grinding times. carbon black was employed to produce pores. the formation of lsm single phase was studied by x-ray ...

This article focuses on perovskite materials for application as cathode material in solid oxide fuel cells. In order to develop new promising materials it is helpful to classify already known perovskite materials according to their properties and to identify certain tendencies. Thereby, composition-dependent structural data and materials properties are considered. Structural data under consider...

Objectives: To assess the effectiveness of mirror therapy (MT) on upper limb (UL) function of sub-acute stroke patients. Methods: This study is a single case experimental design with two participants. Twenty minutes of MT were implemented four times a week over a period of four weeks. For baseline phase, repeated measurements were performed six times for one participant and four times for the ...

Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as "alternative" is highly controversial. Most of the recent and existing alternative sources of energy are discussed below. K...

Two glass-ceramics sealants for solid-oxide fuel cells (SOFC) in the system BaO/SrO-MgO-B2O3-SiO2 have been analysed according to relevant sealing parameters such as sintering and crystallization of glass powders dilatation viscosity evolution with glass-ceramic compacts. Special emphasis is given kinetics mechanism, crystalline phases formed role whole process. The slower rate strontium-contai...

Rapid load transition is an essential requirement for integrated energy systems to maintain grid resilience as more renewable resources are added the grid. Integrated solid oxide fuel cell – gas turbine (SOFC-GT) can provide high efficiency and low carbon emissions over a broad range of turndown. These hybrids also have potential enable rapid response. The challenge has been demonstrate effecti...
