A process for dissolving nuclear fuel, in particular irradiated nuclear fuel, comprising immersion of the nuclear fuel in a nitric acid solution. This dissolution process further comprises mechanical milling of the nuclear fuel, this mechanical milling being performed in the nitric acid solution during the immersion. The disclosure also relates to the use of a mill equipped with mechanical milling structure to implement the dissolution process.

Method for dissolving nuclear fuel

This invention relates to a method for preparing an air electrode based on PrNiOwith 0&#x2266;x&#x3c;2, comprising a step consisting in sintering a ceramic ink comprising PrNiOand a pore-forming agent at a temperature above 1000&#xb0; C. and below or equal to 1150&#xb0; C. This invention also relates to the air electrode thus obtained and its uses.

Method for producing an air electrode, the electrode thus obtained and its uses

The present invention relates to a method for preparing an electrode-supported electrochemical half-cell including a step consisting in subjecting a green electrode layer on which a precursor gel of the electrolyte or a precursor thereof is deposited to sintering at a temperature of less than or equal to 1350&#xb0; C.

Method of preparing an electrochemical half-cell

A hydrogen-producing cell comprising a cell of a high temperature steam electrolyzer or HTSE comprising a porous cathode () and a porous anode () on either side of a dense and gases-impervious anion conducting electrolyte (), wherein said cell of the high temperature steam electrolyzer is directly coupled, in series, with a cell of an electrochemical pump comprising a porous anode () and a porous cathode () on either side of a dense and gases-impervious proton conducting electrolyte (), at the cathode () of the cell of the high temperature steam electrolyzer and at the anode () of the electrochemical pump.

Hydrogen-producing cell comprising a cell of a high temperature steam electrolyzer

An electrolyte plate for an electrochemical system including a first face and a second face, being opposite each other, of largest surface area, the first face including linear parallel ribs and the second face including linear parallel ribs. The plate thus exhibits an increased rigidity without substantially increasing the thickness thereof.
