Electrochemical converter

摘要

An electrochemical converter with proton membrane includes a plurality of electrochemical unitary cells connected in series and arranged on a carrier tape elongated along a longitudinal axis, a first face of which has anodes that receive hydrogen and a second face has cathodes that receive air, wherein the hydrogen circulates in a flow parallel to the longitudinal axis of the aforementioned tape and the air circulates in a flow transverse to the longitudinal axis of the aforementioned tape, and separation means dividing the air flow into a cooling flow having no contact with the cathodes and a cathodic reaction flow in contact with the cathodes.

1. An electrochemical converter with proton membrane comprising a plurality of electrochemical unitary cells connected in series and arranged on a carrier tape elongated along a longitudinal axis, a first face of which has anodes that receive hydrogen and a second face has cathodes that receive air, wherein the hydrogen circulates in a flow parallel to the longitudinal axis of said tape and the air circulates in a flow transverse to the longitudinal axis of said tape, separation means dividing the air flow into cooling flow having no contact with the cathodes and a cathodic reaction flow in contact with the cathodes the tape carrying the cathodes and a second face opposite to the first face and providing said cathodic reaction flow on the first face in contact with the face carrying the cathodes of said tape and providing said cooling flow on the second face not in contact with said face carrying the cathodes,
wherein the separation means are made of a corrugated film, the corrugations of which are arranged perpendicular to the longitudinal axis of the carrier tape and wherein the ratio of reaction air flow rate versus cooling air flow rate is configured with the geometry of the corrugated film by comprising asymmetric corrugations making one passing section larger on one side than the other.
