Abstract

PCT No. PCT/DK94/00084 Sec. 371 Date Oct. 26, 1995 Sec. 102(e) Date Oct. 26, 1995 PCT Filed Mar. 1, 1994 PCT Pub. No. WO94/20998 PCT Pub. Date Sep. 15, 1994A 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 cm2 at 40 mV. Furthermore, a mechanically stable structure is obtained.
