Abstract

1,113,839. Generators operating by electromagnetic interaction with fluids. COMMISSARIAT A L’ENERGIE ATOMIQUE. 16 May, 1966 [25 May, 1965], No. 21705/66. Heading H2A. [Also in Division B3] A composite electrode for an MHD generator comprises a first conductive zone formed preferably of zirconia, thoria, or lanthanum chromite and a second zone constituted by a thermally and electrically conductive metal box which is cooled by an internal flow of water, the box being separated from the first zone by a bonding layer and being fitted with metallic members at the top portion to provide mechanical and electrical contact between the two zones. The first zone may be coated with a boride having good thermionic emissivity. The bonding layer may be formed of a carbide or a boride of the metal of the oxide which constitutes the first zone, or it may be a noble refractory metal selected from platinum, rhodium or iridium or an alloy thereof. The top of the box may be flat or it may have a depression of trapezoidal cross-section or it may have channels of parallel-sided or dovetail cross-section.
