Investigating the performance of catalyst layer micro-structures with different platinum loadings

Conference Khakaz-Baboli, Moben ; Harvey, David ; Pharoah, Jon - ECS Transactions

In this study a four-phase micro-structure of a PEFC catalyst layer was reconstructed by randomly placing overlapping spheres for each solid catalyst phase. The micro-structure was mirrored to make a micro-structure. A body-fit computational mesh was produced for the reconstructed micro-structure in OpenFOAM. Associated conservation equations were solved within all the phases with electrochemical reaction as the boundary condition at the interface between ionomer and platinum phases. The study is focused on the platinum loading of CL. The polarization curves of the micro-structure performance have been compared for different platinum loadings. This paper gives increased insight into the relatively greatermore » losses at decreased platinum loadings.« less

Atomically dispersed metal–nitrogen–carbon catalysts for fuel cells: advances in catalyst design, electrode performance, and durability improvement

Journal Article He, Yanghua ; Liu, Shengwen ; Priest, Cameron ; ... - Chemical Society Reviews

The urgent need to address the high-cost issue of proton-exchange membrane fuel cell (PEMFC) technologies, particularly for transportation applications, drives the development of simultaneously highly active and durable platinum group metal-free (PGM-free) catalysts and electrodes. The past decade has witnessed remarkable progress in exploring PGM-free cathode catalysts for the oxygen reduction reaction (ORR) to overcome sluggish kinetics and catalyst instability in acids. Among others, scientists have identified the newly emerging atomically dispersed transition metal (M: Fe, Co, or/and Mn) and nitrogen co-doped carbon (M–N–C) catalysts as the most promising alternative to PGM catalysts. Here, we provide a comprehensive review ofmore »« less

The Impact of Ink and Spray Variables on Catalyst Layer Properties, Electrolyzer Performance, and Electrolyzer Durability

Journal Article Alia, Shaun M. ; Reeves, Kimberly S. ; Baxter, Jefferey S. ; ... - Journal of the Electrochemical Society (Online)

In proton exchange membrane-based electrolysis, cell-level performance and durability is affected not only by individual components, but also by how those components are integrated into membrane electrode assemblies. In this study, several ink and ultrasonic spray parameters are evaluated for their effect on catalyst layer properties, electrolyzer performance, and electrolyzer durability. The relative impact of these variables on kinetic and ohmic loss were revealed and linked to catalyst layer morphology. Ionomer loading and dispersion principally affect kinetics and accelerate kinetic loss over time. Catalyst layer uniformity, however, tends to affect ohmic loss, where poor catalyst-transport layer contact adds resistances, increasesmore »« less

A high-performance and durable direct NH₃ tubular protonic ceramic fuel cell integrated with an internal catalyst layer

Journal Article Pan, Yuxin ; Zhang, Hua ; Xu, Kang ; ... - Applied Catalysis. B, Environmental

Nickel-based cermet anode-supported protonic ceramic fuel cells (PCFCs) show great potential for direct utilization of ammonia. However, the insufficient activity of anode and the deterioration of anode activity/durability caused by the undesired interaction between nickel and ammonia greatly limit the application. Here, we report tubular PCFCs embedded with a catalytic iron layer. Such cells show peak power densities of 1.507 W cm^-2 and 1.078 W cm^-2 at 700 °C when using H₂ and NH₃ as fuel, respectively, which are the highest tubular PCFC performance so far ever reported. In addition, the stability of cells with the catalyst layer has beenmore »« less

Effective Transport Properties Accounting for Electrochemical Reactions of Proton-Exchange Membrane Fuel Cell Catalyst Layers

Conference Pharoah, Jon ; Choi, Hae-Won ; Chueh, Chih-Che ; ... - ECS Transactions

There has been a rapidly growing interest in three-dimensional micro-structural reconstruction of fuel cell electrodes so as to derive more accurate descriptors of the pertinent geometric and effective transport properties. Due to the limited accessibility of experiments based reconstruction techniques, such as dual-beam focused ion beam-scanning electro microscopy or micro X-Ray computed tomography, within sample micro-structures of the catalyst layers in polymer electrolyte membrane fuel cells (PEMFCs), a particle based numerical model is used in this study to reconstruct sample microstructure of the catalyst layers in PEMFCs. Then the reconstructed sample structure is converted into the computational grid using body-fitted/cut-cellmore »« less
