Abstract

The present method of forming a polar plate comprises: a stamping step: implemented by a stamping press, which includes a stamping tool mounted on a slider moved by vertical reciprocating movement; and during which a network of channels for circulating fluids is stamped on the strip; and a downstream step subsequent to the stamping step and implemented by a downstream press; wherein: once the channel network is stamped on the strip, while the strip is held clamped in the stamping tool, a reference mark is formed on the strip by means of a marking tool carried by the slider; and during the downstream step, the strip is positioned with respect to the downstream press by means of positioning members mounted on the downstream press and which cooperate with the reference mark.

Abstract

The invention relates to a method in which an effluent comprising catalytic ink residues and water or a hydro-alcoholic mixture of water and alcohol A is produced, which is heated to a temperature point and to a pressure causing the evaporation of water and/or alcohol A and the concentrate is recovered. The latter contains the catalytic particles and the electrolytic polymer substantially in their known relative amounts in the catalytic ink. This concentrate is then used to produce a fresh ink, in particular by adding this concentrate to a production ink.

Abstract

The invention relates to a method for recycling residues of a catalyst ink comprising catalyst particles, an electrolyte polymer, and water. The method comprises providing an effluent containing the catalyst ink residues, filtering the effluent through a filter membrane, leading to the formation of a retentate containing the catalyst particles contained in the effluent, all or part of the electrolyte polymer, and water, and then, preferably, the diafiltration thereof by adding water. Filtration and diafiltration are preferably tangential and dynamic. The ink residues may originate from the cleaning of a catalyst ink production and/or deposition plant, or from the dissolution of ink layers on the surface of a fuel cell membrane electrode assembly. The invention further relates to a composition for recycling and to a method for producing a new ink incorporating the composition for recycling.

Abstract

This method for detecting a hydrogen leak applies to a fuel cell system (10) comprising a fuel cell (12); a hydrogen supply system (30) comprising a reservoir (32) and the supply circuit (34) connecting the reservoir to the anode compartment (16) of the fuel cell and comprising an ejector (36) of Venturi type; a recirculation circuit (60) for recirculating unconsumed hydrogen between the anode compartment of the cell and the Venturi-type ejector (36), the recirculation being driven by the Venturi-effect ejector. The method comprises steps involving calculating the total flow rate of hydrogen consumed; calculating the flow rate of hydrogen admitted to the ejector; determining the leak rate as the difference between the flowrate of hydrogen admitted and the total flow rate of hydrogen consumed; and detecting a potential leak of hydrogen by comparing the leak rate against at least a threshold value, such that the method detects all of the hydrogen leaks that occur in the system downstream of the ejector.

Abstract

The invention relates to a method for running in a PEM fuel cell, the method comprising at least a first running-in phase (P2), followed by an operation of reversing the direction of the dihydrogen and air streams (P3), and then a second running-in phase (P4). The running-in phases each comprise a step (4) of stabilizing the fuel cell in which the current density produced by the cell is kept constant at a low value for a given duration, followed by an oxygen depletion step (5), during which the current density is kept constant at a minimum value, lower than or equal to the low value, and during which the air supply is at least partially interrupted, being adjusted so as to obtain a cathode stoichiometry coefficient of strictly less than 1. The oxygen depletion steps of the first and second running-in phases end when the cell voltage of the fuel cell reaches a predefined threshold voltage.

Abstract

The invention relates to a fuel cell (10) which comprises a casing, a stack of electrochemical cells, a stationary end plate and a movable end plate (16) clamping the stack between them, and a guide system (30) for guiding the movable end plate, which guide system limits the movement of the movable end plate perpendicularly to a stacking direction (X). In order to control the positioning of the movable end plate, the guide system comprises at least one compression member (32) exerting a compression force (E32) on the movable end plate in a compression direction (Y), two guide members (36A, 36B) attached to the movable end plate, and two oblique supports (38A, 38B) which are attached to the casing, extend parallel to the stacking direction, and are oblique with respect to the compression direction and with respect to a centring direction (Z). Under the effect of the compression force, the guide members bear against the oblique supports and centre the movable end plate, parallel to the centring direction, with respect to the casing.

Abstract

This method for detecting a hydrogen leak applies to a fuel cell system (10) comprising a fuel cell (12); a hydrogen supply system (30) comprising a reservoir (32) and the supply circuit (34) connecting the reservoir to the anode compartment (16) of the fuel cell and comprising an ejector (36) of venturi type; a recirculation circuit (60) for recirculating unconsumed hydrogen between the anode compartment of the fuel cell and the venturi-type ejector (36), the recirculation being sustained by the venturi-effect ejector. The method comprises steps involving calculating the total flow rate of hydrogen consumed; calculating the flowrate of hydrogen admitted to the injector; determining the leak rate as the difference between the flowrate of hydrogen admitted and the total flowrate of hydrogen consumed; and detecting a potential leak of hydrogen by comparing the leak rate against at least a threshold value, such that the method detects all of the hydrogen leaks that occur in the system downstream of the ejector.
