摘要:
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.

摘要:
An electrolyte plate for an electrochemical system including a first and a second face opposite to each other of larger surface areas, both faces being separated by a given distance. The first face includes linear protrusions and the second face includes linear recesses, the protrusions and the recesses being substantially parallel to each other. Each protrusion is superposed to a recess along a direction substantially orthogonal to a mean plane of the plate, the distance separating a bottom of each recess from a vertex of the superposed protrusion being substantially equal to the distance between the first and the second face so that the electrolyte plate has a substantially constant thickness.
