摘要： A proton conducting electrolyte membrane comprising a ceramic electrolyte layer including an inorganic proton conductor and a ceramic protective layer formed on at least one surface of the ceramic electrolyte layer and having proton conductivity; a membrane electrode assembly including the proton conducting electrolyte membrane; and a proton conducting ceramic fuel cell including the membrane electrode assembly. In the proton conducting electrolyte membrane, the ceramic protective layer may have an improved chemical bond with the ceramic electrolyte layer compared with a Pd metal protective layer, such that interlayer delamination may be lessened. Also, compared with a Pd metal protective layer, the ceramic protective layer is more appropriate for ceramic electrolytes such as BYZ and BYC that transmit protons or simultaneously transmit protons and oxygen ions used in a fuel cell operating at a temperature range of about 200 to about 500° C., for example, about 250 to about 500° C.
