A computational method for determining a location and an amount of a transition metal M in surface facets of a Pt—M alloy using a density functional theory includes receiving a particle size and a surface facet distribution of the Pt—M alloy and a total concentration of M in the Pt—M alloy; calculating a total number of M atoms in the Pt—M alloy based on the particle size and the surface facet distribution of the Pt—M alloy and the total concentration of M in the Pt—M alloy; and predicting a mixing energy between Pt and at least one of the total number of M atoms in a subsurface layer of each of the surface facets of the Pt—M alloy when Pt is mixed with the at least one of the total number of M atoms.

Fuel cell alloy bipolar plates. The alloys may be used as a coating or bulk material. The alloys and metallic glasses may be particularly suitable for proton-exchange membrane fuel cells because of they may exhibit reduced weights and/or better corrosion resistance. The alloys may include any of the following AlCuTi, AlFeNi, AlMnNi, AlNiTi, CuFeTi, CuNiTi, AlFeSi, AlMnSi, AlNiSi, NiSiTi, and CFeSi. The alloys or metallic glass may be doped with various dopants to improve glass forming ability, mechanical strength, ductility, electrical or thermal conductivities, hydrophobicity, and/or corrosion resistance.

An electrostatic charging air cleaning device. The device includes a pre-charger configured to generate a corona discharge to electrostatically charge particulate matter in an air stream. The device further includes a separator downstream from the pre-charger configured to convey the electrostatically charged particulate matter and formed of an insulative material. The device also includes a collection electrode configured to receive and to absorb the conveyed electrostatically charged particulate matter. The collection electrode includes a substrate material and a coating layer coated onto the substrate material. The coating layer includes a carbon black material and a polymeric binder. The substrate material is a metal plate including mechanical perforations.

A fuel cell stack includes a first end region, a second end region, and a middle region. At least one of a first number of fuel cell units in the first end region is a first fuel cell unit including a membrane electrode assembly (MEA) with a first catalyst material on either or both an anode and a cathode of the first fuel cell unit. At least one of a second number of fuel cell units in the second end region is a second fuel cell unit including an MEA with a second catalyst material on either or both an anode and a cathode of the first fuel cell unit. The middle region is situated between the first and the second end region. At least one of a third number of fuel cell units in the middle region is a third fuel cell unit including an MEA with a third catalyst material on either or both an anode and a cathode of the first fuel cell unit. At least one of the first, the second, and the third catalyst material are different.

A proton exchange membrane fuel cell includes an anode catalyst layer, a cathode catalyst layer, a proton exchange membrane separating the anode catalyst layer from the cathode catalyst layer, an oxygen inlet configured to supply oxygen to the cathode catalyst layer, and a hydrogen inlet separate from the oxygen inlet and configured to supply hydrogen to the anode catalyst layer. The fuel cell is operable to convert the hydrogen from the hydrogen inlet to hydrogen ions at the anode catalyst layer and to produce an H2O byproduct at the cathode catalyst layer where the oxygen reacts with the hydrogen ions. The fuel cell includes a water outlet for the H2O byproduct that is separate from the oxygen inlet.
