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.

Provided are a method of preparing a fuel cell and a membrane electrode assembly prepared by the method. The method includes preparing a substrate, forming a buffer layer having a single crystalline structure on the substrate, forming a proton conducting solid perovskite electrolyte membrane on the buffer layer, forming a first electrode on one surface of the proton conducting solid perovskite electrolyte membrane, etching the substrate, and forming a second electrode on the opposite surface of the one surface of the electrolyte membrane. Thus, the method of preparing a fuel cell can improve ion conductivity of an electrolyte membrane at a low temperature and a membrane electrode assembly of a fuel cell prepared by the method can improve ion conductivity at a low temperature.

Provided is a liquid-gas separator of a direct liquid feed fuel cell. The liquid-gas separator includes an empty ball shaped main body; a gas extraction membrane which is attached to an opening formed in the main body, and selectively extracts gas from the main body; an inlet which is formed in the main body and guides the liquid and gas into the main body; an outlet which is formed on the main body and guides the liquid to the outside of the main body; and a flexible tube having a hollow structure, one end of which is connected to the outlet and the other end of which is immersed in the liquid fuel.
