摘要： A fuel cell stack (31) includes a plurality of fuel cells (9) each having an electrolyte such as a PEM (10), anode and cathode catalyst layers (13, 14), anode and cathode gas diffusion layers (16, 17), and water transport plates (21, 28) adjacent the gas diffusion layers. The cathode diffusion layer of cells near the cathode end (36) of the stack have a high water permeability, such as greater than 3x10-4 g/(Pa s m) at about 80°C and about 1 atmosphere, whereas the cathode gas diffusion layer in cells near the anode end (35) have water vapor permeance greater than 3x10-4 g/(Pa s m) at about 80°C and about 1 atmosphere. In one embodiment, the anode gas diffusion layer of cells near the anode end (35) of the stack have a higher liquid water permeability than the anode gas diffusion layer in cells near the cathode end; a second embodiment reverses that relationship.

摘要： An example of a stable electrode structure is to use a gradient electrode that employs large platinum particle catalyst in the close proximity to the membrane supported on conventional carbon and small platinum particles in the section of the electrode closer to a GDL supported on a stabilized carbon. Some electrode parameters that contribute to electrode performance stability and reduced change in ECA are platinum-to-carbon ratio, size of platinum particles in various parts of the electrode, use of other stable catalysts instead of large particle size platinum (alloy, etc), depth of each gradient sublayer. Another example of a stable electrode structure is to use a mixture of platinum particle sizes on a carbon support, such as using platinum particles that may be 6 nanometers and 3 nanometers. A conductive support is typically one or more of the carbon blacks.

摘要： A unitized electrode assembly (10; 110; 210; 310; 410) for a fuel cell includes, in addition to an anode catalyst layer (54; 254) and a cathode catalyst layer (56; 256), a polymer electrolyte membrane (52) having an acid functional group normally including H + ions and an edge seal (66; 166; 266, 366, 466) containing alkali metal ions in a form, concentration, and/or location for delivery and dispersion into the membrane. The edge seal of the unitized electrode assembly is proximate, and typically contacts, the peripheral edge region (68) of the membrane in ion-transfer relation therewith, and alkali metal ions leach into the membrane during fuel cell operation to provide a desired ion exchange in the membrane. The alkali metal ions contained by the edge seal may be Li + , Na + , K + , Rb + , and/or Cs + , and may be included as a dopant with the material of the edge seal during its formation, or may be included as a discrete component of the edge seal, as by an ion-doped strip of membrane material contained by the edge seal. The edge seal thus serves as a "reservoir" of the alkali metal ions for release to the polymer electrolyte membrane for increased durability.

摘要： A fuel cell includes an anode, a cathode and an electrode assembly. A heating element is arranged proximate to the cell. The heating element includes a variable electrical resistance relative to a temperature to which the heating element is exposed. The heating element is electrically resistive at a first temperature and electrically conductive at a second temperature greater than the first temperature. In one example, the heating element is part of an electrical circuit that receives power at both the first and second temperatures. The presence of the heating element becomes generally transparent in the circuit once the heating element reaches the second temperature. In one example, the heating element is constructed from a transition metal oxide, such as vanadium oxide, which transitions from electrically resistive to electrically conductive in a very narrow temperature range.
