ABSTRACT:
A high-temperature fuel cell has at least one electrically insulating covering. The electrically insulating covering contains at least two layers which are disposed one on top of the other and are each formed of an electrically insulating ceramic material. The composition of the ceramic material of one layer is different from the composition of the ceramic material of the other layer. This results in optimization of the insulation characteristic and the adhesion of the electrically insulating covering. A method is also provided for producing a high-temperature fuel cell having at least one electrically insulating covering.
