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 bench for mechanical characterisation of a battery cell by applying a compression force includes a frame having a first compression plate, a movable element having a second compression plate opposite the first compression plate, a compression spring for applying a compression force to the cell between the first and second compression plates, a force sensor inserted between the movable element and the spring, and movement sensors measuring the movement between the first and second compression plates. The first compression plate includes a projecting compression zone with an area equal to a portion of interest of the cell and the frame includes a recess surrounding a thicker frame in the frame forming a pedestal supporting the first compression plate.
