NICOP - Development of non-Pt electrocatalysts for hydrogen Proton Exchange Membrane Fuel Cells
Abstract
The objective of the present study is to develop a highly active and stable graphene based catalyst for oxygen reduction in PEM fuel cells. The Nitrogen doped graphene (N-~~G) will be synthesized by hydrogen exfoliation of graphitic oxide with the required nitrogen based polymers for the incorporation of nitrogen within the graphene matrix. Palladium -~~transition metal (PdTM) alloy nanoparticles will be dispersed on the N-~~G by a simple single-~~step process using the precursors. The synthesized catalysts will be characterized using different analytical methods to identify the active reaction sites for oxygen reduction reaction. The catalyst performance will be evaluated by preparing single PEM fuel cell. Firstly, at the cathode side, 0.1 mg/cm2 of Pt/N-~~G will be used and at the anode side, the loading of PdTM alloy/N-~~G catalyst will be optimized in order to get the best performance. Secondly, 0.1 mg/cm2 of Pt/N-~~G will be used at the anode and the loading of PdTM alloy/N-~~G catalyst will be optimized at the cathode in order to get the best performance. These results will be used to identify the active reaction sites for oxygen reduction reaction and to develop PdTM alloy decorated N-~~G electrocatalysts for hydrogen Proton Exchange Membrane Fuel Cells. b) Specify relevance to ONR, the US Naval Research Enterprise, and/ or other US DoD. Identify alignment with the US Naval and/ or Marine Corp Science & Technology Strategic Plan. Department of Energy and the US Naval Research Enterprise target a Platinum group metal (PGM) total content (both electrodes) of 0.2 g/kW (rated) and a total Platinum 1 c) Identify all US collaborators especially if there are any ONR Program Officers (and relevant ONR Code) that are collaborators (even if the ONR PO is not actively contributing funds to the effort).NILd) State the desired outcomes of this research effort (e.g., conference presentation, website, journal article, algorithm, tool, additional research).Journal articles, additional research
