Sealing compound for producing sealing layer for gas-sealed connection between high temperature fuel cells, has liquid precursor, which is converted into ceramic binding agent by organic peroxid and glass powder slurried in liquid precursor

摘要

The compound has a liquid precursor, which is converted in a ceramic binding agent by using an organic peroxid, and a glass powder slurried in the liquid precursor. The ratio of the weight portion of the precursor and the glass powder is in the range of 1:1 to 1:4. The mass ratio of the components of the compound is selected such that expansion co-efficient of the compound is 10x10 -6 meter/Kelvin. The compound is designed as a layer arranged on an upper side of a housing upper part (110). Independent claims are also included for the following: (1) an electrically insulated sealing unit for gas-sealed connection of two fuel cells (2) a fuel cell block including a set of fuel cells and a sealing unit.
