Abstract: A solid oxide fuel cell having a tubular metal support an open end. A first electrode is deposited on the metal support, an electrolyte is deposited on the first electrode, and a second electrode is deposited on the electrolyte. The open end of the metal support is in communication with a fuel supply and attached to an external structure of the fuel supply by threads.

Abstract: An electroluminescent material comprising at least one electroluminescent compound supported on a matrix, wherein the matrix is selected from among microporous and mesoporous materials, selected from among zeolites, porous oxides, molecular sieves, silicoaluminophosphates and aluminosilicates, the electroluminescent compound is selected from among polymers derived from polyphenylenevinylene, complexes of earth metal ions with 8-hydroxyquinoline and combinations thereof, and where the electroluminescent compound is housed in interior spaces of the matrix. These electroluminescent materials possess excellent properties in terms of chemical stability towards the environment (oxygen, humidity, CO2, etc.), durability (number of electroluminescent cycles under aerobic conditions), control of the state of aggregation (isolated or being associated in pairs or more) of aromatics.
