A method of monitoring operation of a reactor system includes causing a chemical reaction to occur within an assembly of the reactor system, and measuring a chemical composition of one or more reactants of the chemical reaction with spatial resolution at a plurality of points along a path within the assembly using a sensor system structured to implement distributed sensing. The sensor system includes an optical fiber sensing member provided at least partially within the assembly, wherein the optical fiber sensing member comprises a functionalized optical fiber based sensor device structured to exhibit a change in one or more optical properties in response to changes in the chemical composition of the one or more reactants.

System and method for monitoring a reactor system using optical fiber based sensors

Described herein are methods of forming an electrocatalyst structure on an electrode, comprising depositing a first layer on the electrode using atomic layer deposition (ALD), wherein the first layer comprises a plurality of discrete nanoparticles of a first electrocatalyst, and depositing one or more of a second layer on the first layer and the electrode using ALD, wherein the one or more second layer comprises a second electrocatalyst, wherein the first layer and the one or more second layers, collectively, form a multi-layer electrocatalyst structure on the electrode. Also described are electrodes having a multi-layer electrocatalyst structure. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Methods for forming electrocatalyst structures and electrodes comprising same

One embodiment includes forming surface-modifying phases on a surface of a functional electrode via atomic layer deposition and controlling the chemistry of constituent phases, the crystalline nature of the constituent phases and the thickness of the surface-modifying phase via the atomic layer deposition such that the thickness is between about 2 nm to about 200 nm. The surface-modifying phases enhances the performance of electrocatalytic activity of the functional electrode and the device.

Nanoscale SOFC electrode architecture engineered using atomic layer deposition

Provided herein is a method for electrocatalyst infiltration of a porous substrate, of particular use for preparation of a cathode for a solid oxide fuel cell. The method generally comprises preparing an electrocatalyst infiltrate solution comprising an electrocatalyst, surfactant, chelating agent, and a solvent; pretreating a porous mixed ionic-electric conductive substrate; and applying the electrocatalyst infiltration solution to the porous mixed ionic-electric conductive substrate.
