Abstract
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.OMEGA.cm.sup.2 at 40 mV. Furthermore, a mechanically stable structure is obtained.
