Abstract: Nanoimprint lithography (NIL) method to fabricate electrodes with high specific Pt surface areas that can be used in fuel cell devices. The Pt catalyst structures were found to have electrochemical active surface areas (EAS) ranging from 0.8 to 1.5 m2g−1 Pt. These NIL catalyst structures include fuel cell membrane electrode assemblies (MEA) that are prepared by directly embossing a Nafion membrane. The features of the mold were transferred to the Nafion® and a thin film of Pt was deposited at a wide angle to form the anode catalyst layer. The resulting MEA yielded a Pt utilization of 15,375 mW mg−1 Pt compared to conventionally prepared MEAs (820 mW mg−1 Pt).

Abstract: A class of materials has advantageous utility in electrocatalytic applications, e.g., fuel cells. The materials circumvent conventional Pt-based anode poisoning and the agglomeration/dissolution of supported catalysts during long-term operation by exploiting the unique physical and chemical properties of bulk metallic glass to create nanowires for electrocatalytic applications, e.g., fuel cell and battery applications. These amorphous metals can achieve unusual geometries and shapes along multiple length scales. The absence of crystallites, grain boundaries and dislocations in the amorphous structure of bulk metallic glasses results in a homogeneous and isotropic material down to the atomic scale, which displays very high strength, hardness, elastic strain limit and corrosion resistance. The melting temperatures of the disclosed bulk metallic glasses are much lower than the estimated melting temperatures based on interpolation of the alloy constituents making them attractive as highly malleable materials.

Abstract: A method is provided. A first layer is provided over a substrate, the first layer comprising a first material. A patterned second layer is applied over the first layer via stamping. The second layer comprising a second material. The second layer covers a first portion of the first layer, and does not cover a second portion of the first layer. The second portion of the first layer is removed via a subtractive process while the first portion of the first layer is protected from removal by the patterned second layer.

Abstract: A method of using inkjet printing (IJP) to deposit catalyst materials onto substrates such as gas diffusion layers (GDLs) that in one application are made into membrane electrode assemblies (MEAs) for polymer electrolyte fuel cells (PEMFC). The inventive IJP method can deposit smaller volumes of water-based catalyst ink solutions with picoliter precision. By optimizing the dispersion of the ink solution, this technique can be used with catalysts supported on different specimens of carbon black.
