A unit cell of a fuel cell may include: a membrane-electrode assembly including a proton exchange membrane, an anode electrode fastened to a first face of the proton exchange membrane, a first flow guide plate positioned facing the anode electrode and including at least one flow channel having a fuel inlet zone, a median flow zone and a fuel outlet zone. The anode electrode may have, at the fuel outlet zone, a tolerance to carbon monoxide pollution greater than its average tolerance to carbon monoxide pollution at the median flow zone and at the fuel inlet zone.

Fuel cell limiting co poisoning and poisoning diagnostic process

A fuel cell, including: first and second electrochemical cells; a two-pole plate arranged between the first and second electrochemical cells, including a conductor support delimiting a first flow channel facing the first electrochemical cell and extending between an air inlet and a water outlet, and including a first conductive coating attached to the conductor support at the air inlet of the first flow channel and including a second conductive coating fastened to the conductor support at the middle part of the first flow channel, the second conductor coating having an electrical surface resistance greater than that of the first conductive coating.

Fuel cell with optimized operation

A fuel cell includes three membrane-electrode assemblies. and first and second bipolar metal plates interposed between the membrane-electrode assemblies. Each of the bipolar plates comprises two metal sheets facing a respective membrane-electrode assembly and fixedly attached by welds. The two metal sheets comprise successive guiding channels for guiding gas extending in a common longitudinal direction. The guiding channels are distributed in a transversal direction The welds are made in bottoms of the guiding channel and include welds of the first bipolar plate and welds of the second bipolar plate. Some of the welds of the first bipolar plate are not superimposed on the welds of the second bipolar plate and are offset longitudinally and transversally relative to the welds of the second bipolar plate.

Fuel cell including bipolar plates having welds not superimposed with welds of adjacent bipolar plates

Bipolar plate for a fuel cell, of the type comprising a cathode bipolar half-plate and an anode bipolar half-plate which are secured to each other, each bipolar half-plate () being constituted by a plate which comprises, in the central portion thereof, an active zone () and, at the peripheral portion thereof, a plurality of cut-outs () which are intended to constitute at least two oxidant units, at least two fuel units and at least two heat-exchange fluid units, at least one bipolar half-plate () comprising at least one connection between a peripheral cut-out () and the active zone (), and comprising, at the periphery thereof, at least one hollow housing () which is intended to receive a connector () for electrical measurement.
