    • The invention relates to stackable high temperature fuel cells which may be combined to give so-called fuel cell stacks and electrically connected to each other in parallel, or in series. According to the invention, said high temperature fuel cells form an electrically-conducting connection between a cathode and an interconnector, which has a sufficiently high electrical conductivity and a chemical and mechanical resistance and stability sufficient enough for temperatures above 800 °C and for the oxidising atmosphere present for the operation of fuel cells. Said high temperature fuel cells have a fuel supply connection on the anode side and an oxidising agent supply connection on the cathode side. The cathode is electrically connected to an interconnector by means of at least one spring elastic contact element. The spring elastic contact element comprises one or more regions exerting a pressure force on regions of the interconnector, whereby said contact element is made form an electrically-conducting ceramic material.
