  • Patent number: 7482082
    Abstract: Electrochemical cell, such as an SOFC, comprising a porous solid electrode (2) in contact with an electrolyte (1), which has been treated so as to become gasproof before the electrode is applied. According to the invention, this contact has been mechanically improved by sintering anchoring particles (3) of for instance TiO2 onto the electrolyte (1). Subsequently, the electrode (2) can be sintered thereon at a temperature lower than hitherto known while still obtaining a sufficient, mechanical attachment in the contact. The latter lowering of the process temperature results in an improved efficiency of the electrode (2), and it allows the use of electrodes which are usually reactive towards the electrolyte at comparatively higher process temperatures.
