Patent ID: 7622212

Claim:
Electrochemical converter ( 1 ) with protonic membrane, comprising a plurality of series-connected, unit electrochemical conversion cells ( 2 a , 2 b , 2 c , . . . ), characterized in that it comprises a first substrate ( 11 , 15 ) comprising the protonic membrane, comprising a first surface ( 11 a ) on which a succession of first deposits is made forming a series of spaced anodes ( 12 a , 12 b , 12 c , . . . ), and a second surface on which a succession of second deposits is made forming a series of spaced cathodes ( 13 a , 13 b , 13 c , . . . ) located opposite said anodes, said anodes and cathodes forming a plurality of unit conversion cells ( 2 a , 2 b , 2 c , . . . ), and in that it comprises connection tracks ( 14 a , 14 b , 14 c , . . . ) between a cathode of one unit cell and an anode of an adjacent unit cell, passing through the first substrate ( 11 , 15 ) between said unit conversion cells, wherein the first substrate comprises a first lateral strip ( 11 ) comprising the deposits, and a second lateral strip ( 15 ), with no deposits, winding along a longitudinal axis (A) on the first lateral strip ( 11 ) and sealed on the first lateral strip so as to enclose the anodes ( 12 a , 12 b , 12 c , . . . ) in a tubular duct that forms a first channeling means ( 3 ) in which the hydrogen circulates.
