20110079966 | ASSEMBLY COMPRISING A SEAL INSERTED BETWEEN TWO COMPONENTS OF DIFFERENT MEAN THERMAL EXPANSION COEFFICIENT, ASSOCIATED SEAL, APPLICATION TO SEALING OF HTE ELECTROLYZERS AND SOFC FUEL CELLS - The invention concerns an assembly typically operating at above 500° C., between two components of different mean thermal expansion coefficients, between which a seal is inserted having a coefficient which differs by a value of at least 1.10 | 04-07-2011 |
20120325654 | HIGH TEMPERATURE ELECTROLYZER (HTE) HAVING A STACK OF ELECTROLYSIS CELLS AND IMPROVED OPERATING RELIABILITY AND HIGH EFFICIENCY - A high-temperature module for electrolysis of water with improved operational safety, in which steam containing at most 1% hydrogen can be made to flow simultaneously in each cathode and in each anode, as a draining gas, of a stack of cells. The stack of cells is housed in a sealed case and a mechanism for clamping by compression of the stack is included. The risks of leaks likely to cause impairments of efficiency and breakages of all or part of a stack EHT electrolyser are reduced, while a high level of efficiency is provided due to the fact that satisfactory electrical conduction is maintained by compression of the stack. | 12-27-2012 |
20120325677 | ELECTROCHEMISTRY METHOD HAVING IMPROVED EFFICIENCY AND ASSOCIATED ELECTROCHEMICAL REACTOR SUCH AS A HIGH TEMPERATURE ELECTROLYSER (EHT) - An electrochemistry method to produce a reaction gas of a lesser molar mass than that of an initial constituent of gas or vapor, according to which the gas or vapor of the initial constituent is made to flow, and the reaction gas is recovered in the path in which the initial constituent is made to flow. At least one vortex is created in a zone upstream from the reaction gas recovery zone, wherein the vortex can separate the produced reaction gas from the initial constituent still present to subject the initial constituent to an electrochemical process in the upstream zone. In a high-temperature water electrolysis application according to the method, by the vortex, the produced hydrogen is separated from the surplus steam to subject the surplus stream to an electrolytic process within the electrolyser itself. | 12-27-2012 |
20130032490 | HIGH TEMPERATURE ELECTROLYZER (HTE) INCLUDING A PLURALITY OF CELLS, HAVING IMPROVED OPERATION IN THE EVENT OF BREAKAGE OF AT LEAST ONE CELL AND DURING AGEING - A process of electrolyzing water at high temperatures implemented by a cell stack reactor, including: a) simultaneously circulating water vapour at each cathode and at each anode as a leaching gas, temperatures of the water vapour at an inlet of each anode and each cathode being lower than high temperatures at which electrolysis is carried out and the water vapour circulating at the anode being at an overpressure with respect to the cathode; b) upon starting the electrolysis, supplying electrical power having a substantially constant electrical voltage across terminals of the stack and maintaining same. In event of breakage of one or more cells, complete destruction of the stack is avoided and high production efficiency is maintained, and efficiency is maintained during ageing. | 02-07-2013 |
20130168238 | HIGH-TEMPERATURE ELECTROLYSER (HTE) WITH IMPROVED OPERATING SAFETY - A high-temperature electrolyser including a stack of electrolysis cells in which steam is made to flow both at a cathode and at an anode. The architecture of the electrolyser is configured to have each cathode inlet end and anode inlet end close to an oxygen, or respectably hydrogen, collection duct portion. With the structure, a buffer volume of steam is created around the oxygen and hydrogen collectors, which therefore constitutes a simple and effective sealing mechanism within the electrolyser. | 07-04-2013 |
20130244136 | DEVICE FORMING A SEAL BETWEEN TWO SPACES HAVING MUTUALLY REACTIVE GASES, AND USE IN HIGH TEMPERATURE STEAM ELECTROLYSIS (HTSE) UNITS AND IN SOLID OXIDE FUEL CELLS (SOFC) - A seal between two spaces able to be occupied by two mutually reactive gases, typically oxygen and hydrogen. A buffer chamber is produced between the two spaces of mutually reactive gases, wherein leaks of reactive gases to the buffer chamber are determined to produce a flow which is mainly of diffusive type, for example by molecular or Knudsen diffusion. Such a seal may, for example, find application to production of a seal in an EHT electrolyser or a fuel cell of SOFC type. | 09-19-2013 |
