Research Statement

Development of improved materials and processing techniques for the manufacture of fuel cells
A major focus of my research activities has been on improving the performance to cost ratio of fuel cell materials and components and development of low temperature Solid Oxide Fuel Cell (SOFC), both through changes to microstructure and composition of the materials and components, and to the manufacturing processes used to produce them. Low-temperature (LT) SOFC’s, aiming for operating temperatures of 550-650°C, are desirable for reducing the cost of applied materials, shorting start-up time and increasing lifetime for SOFC’s. The key obstacles of the development of these LT SOFC’s are high ohmic resistance and high electrode overpotentials, resulting in low power output density. I developed approaches to overcome these problems. The first is to reduce the electrode polarization resistance by using Co-rich perovskite materials, like La0.6Sr0.4CoO3 (LSC) or SSCO as cathode. The second approach is to introduce a thin and dense CGO-barrier layer between this cathode and the thin 8YSZ electrolyte. The third method is the modification of the fabrication process of the anode substrate, aiming for controlled microstructure with high porosity. A major component of this research theme has been the development of new manufacturing processes for solid oxide fuel cell (SOFC) and Proton Exchange Membrane Fuel Cell (PEMFC) components that can potentially lower the cost of the materials and processing when compared to traditional fabrication techniques. These processes are primarily based on thin film technologies such as reactive spray deposition technology (RSDT), PVD and plasma spray processing. RSDT flame based processing can produce fuel cell layers more rapidly than traditional techniques, and with no need for high-temperature sintering steps. RSDT can therefore potentially reduce both the manufacturing cost and capital cost required, as well as the material costs, by allowing the use of inexpensive stainless steel interconnect materials. The technique is also easy to automate and scale up for mass production, thus potentially further lowering cost.

Development of Low Pt loading catalyst layer and Pt alloys for PEM catalyst
The focuses of this program is on an adaptation of the Reactive Spray Deposition Technique for PEM Catalyst layer fabrication. It is now possible to co-deposit an entire low loading (<0.05mg/cm2 Pt) thin film (<0.5-3um) catalyst layer directly from precursors with this approach. The RSDT manufactured catalyst layer has a performance of 1 A/cm2 at 0.6V with 0.05mg/cm2 Pt cathode loading, in H2/O2 with 100 %RH, which is higher than the best low loading sputtered catalyst layers that have been published at 0.1mg/cm2 Pt loading. The broader goal of this program is to investigate the interplay of manufacturing, microstructure and performance for the creation of thinner catalyst layers.
