Abstract: The present invention relates to compositions in the form of precursor glass powders, pastes and preforms comprising said precursor glass powders, and glass-ceramics produced from the precursor glass powders, pastes or preforms. The present invention also relates to a method of forming a seal between a first and second material with a glass-ceramic, and a joint comprising a first material, a second material and a glass-ceramic sealing material joining the first and second materials together.
Abstract: A process for the preparation of a membrane electrode assembly comprising providing, in the following layer order, (I) a green supporting electrode layer comprising a composite of a mixed metal oxide and Ni oxide; (IV) a green mixed metal oxide membrane layer; and (V) a green second electrode layer comprising a composite of a mixed metal oxide and Ni oxide; and sintering all three layers simultaneously.

Abstract: A process for direct compression of hydrogen separated from a hydrocarbon source is described herein. The process comprises a first zone wherein a hydrocarbon reaction that produce hydrogen occurs, a ceramic proton conductor which under an applied electric field transport hydrogen from said first zone to said second zone, and a second zone where compressed hydrogen is produced. The heat energy generated by ohmic resistance in the membrane is partially recuperated as chemical energy in the hydrocarbon reforming process to generate hydrogen.
