摘要: Cellule à combustible à l'état solide permetttant d'oxyder du CH4, dans laquelle l'électrolyte à l'état solide est préférablement formé par YS2 (oxyde de zirconium stabilisé par de l'yttrium). On applique un oxyde métallique surfactif sur l'électrolyte puis on applique une mince couche de céramique à base de CeO2 qui servira d'anode. Si on le désire, on peut ajouter du MgO afin d'améliorer la stabilité du volume.

摘要: A solid oxide fuel cell includes a cathode, a YSZ-electrolyte, and an anode, where the cathode is formed by a mixture of LSM and YSZ. According to the invention the content in the cathode of YSZ amounts to 20 to 75 % by weight, whereby it is possible to reduce the polarisation resistance to 0,08 Φ cm2 at 40 mV. Furthermore, a mechanically stable structure is obtained.

摘要: An electrochemical cell, such as an SOFC cell, comprising a nickel based electrode structure, such as in form of an NI/YSZ anode, to which Mn has been added. According to the invention, the added amount of Mn of the part of the anode extending less than 20 νm from the electrolyte represents 0.5 to 5 metal atom %. As a result, the efficiency of the electrode is increased, said efficiency typically being defined by the power loss associated with the electrode process, the electric conductivity of the electrode and the catalytic activity of said electrode.

摘要: Solid state fuel cell for oxidation of CH4, where the solid state electrolyte is preferably formed by YSZ (yttrium stabilized zirconium oxide). A surfactive metal oxide is applied onto the electrolyte followed by application of a thin layer of CeO2-based ceramics serving as an anode. If desired, MgO can be added in order to improve the volume stability.
