摘要： The invention is relative to a membrane-electrode assembly for fuel cells, comprising a state of the art ion-exchange polymeric membrane and state of the art gas diffusion electrodes, whose electrochemical properties are modified through the addition of a hydrophilic component localized in correspondence to one or both the electrodic interfaces and/or one or both the external surfaces of the membrane. The modified membrane-electrode assembly is characterized by high protonic conductivity and high efficiency even in the presence of small quantities of carbon monoxide, or of other contaminants contained in the fuel, even at temperatures as low as 100° C., being also suitable for medium temperature (100–160° C.) operation at relative humidity level lower than saturation.

摘要： The invention describes a method and the relevant devices for permitting an operation stable with time of a stack of membrane fuel cells fed with air and a gas containing hydrogen and at least 100 ppm of carbon monoxide, characterised in that it provides for an oxidising condition at the anodes of said cells in a self-adjusting continuous way or sequentially discontinuous way. Different embodiments of the invention are illustrated wherein the oxidising condition is obtained by adding to the gas containing hydrogen and carbon monoxide, oxygen produced in an electrolysis cell integrated to the fuel cell stack, or by flowing air through porous areas obtained in the bipolar plates or by resorting to high gas diffusion rate membranes, wherein the air flow rate is regulated in both cases by adjusting the pressure differential existing between air and the gas containing hydrogen and carbon monoxide. According to a further embodiment of the method of the invention, the oxidising condition is obtained by sequentially short-circuiting the fuel cell stacks provided with external contacts connected to a control unit.

The method of the invention provides dissembling the electrochemical generator (1) once the presence of a damaged elementary cell (2, 21) is detected. Subsequently, the method of the invention provides repairing/replacing the damaged cell for later reassembling the electrochemical generator (1, 20) reusing the original current collectors/distributors (7, 22). to achieve this, while reassembling the electrochemical generator (1, 20), a mechanical means for adapting (8, 12, 13, 14, 15) is inserted between each conducting sheet (3) and the respective current collector/distributor (7, 21). Such mechanical means may consist in metallic meshes, metallic textiles, interwoven fibers, foraminous sheets or expanded sheets, thin sealing gaskets, sealing gaskets provided with sealing rings on a surface thereof, sealing gaskets made of an elastic material with low elasticity modulus.
