Descrição

Descrição geral

LSGM is an electrolyte material for intermediate temperature (below 800^oC ) solid oxide fuel cells (IT-SOFC). LaGaO₃ based pervoskite; doped with strontium and magnesium (LSGM) is known to exhibit high oxide ionic conductivity, on account of the high concentration and mobility of oxygen vacancies LSGM-8282 can be synthesized by solid state reaction between La₂O₃, MgO, SrCo₃ and Ga₂O at temperatures > 1000^oC. Other known methods of producing LSGM are combustion synthesis, coprecipitation route, Pechini method for powder. Pechini method is popularly used in producing LSGM for solid oxide fuel cells (SOFCs).

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Aplicação

World-wide a number of activities are concerned with the optimization and development of cell materials and microstructures with the aim of reducing the solid oxide fuel cell (SOFC) operating temperatures. Reducing operating temperatures not only increases the life time of SOFC but also reduces cost of the total system.
