The present invention relates to a fuel cell element having an active core interposed between a first and second conducting plate, wherein at least the first conducting plate is made from an alloy having, in percentages by weight, 24.0 to 27.0% nickel; 13.5 to 16.0% chromium; 1.90 to 2.35% titanium; 1.0 to 1.5% molybdenum; 0.10 to 0.50% vanadium; at most 0.08% carbon; at most 2.0% manganese; at most 1.0% silicon; at most 0.35% aluminum; at most 0.03% sulphur; and at most 0.01% boron, the balance consisting of iron and impurities.

Conducting plates for fuel cell elements

A method is provided for manufacturing a bundle of plates for a heat exchanger made up of a stack of plates. The method includes reducing by machining the initial thickness of each plate by making at least at the periphery of the plate, at least one connecting shoe having a height greater than the thickness of the machined plate, forming on the central portion of the plate, corrugations, to be superposed pairwise on the plates, connecting the shoes in contact with the plates of each pair through a weld bead, superposing the pairs of plates and connecting the shoes in contact with the pairs of plates through a sealed weld bead by arranging a superposition of open or closed ends for alternate inflow or outflow of said fluid.

Method for manufacturing a bundle of plates for a heat exchanger

A condenser-type heat exchanger having a set of welded plates that together define fluid systems that interpenetrate each other, comprises at least two modules of welded plates. Each module presenting an independent cooling system (CF, CF), fluid (CF) being preferably colder than fluid (CF), and a connecting chamber that connects the two modules in series in the system of fluid to be condensed such that the direction in which the fluid to be condensed flows is reversed when it changes from one module to the next module.
