Grant Description: NOTE: This descriptive area provides an overview ofArea of Interest 4 only.YOU MUST READ THE ENTIRE FUNDING OPPORTUNITY ANNOUNCEMENT DOCUMENT FORDETAILSON ADDITIONAL INFORMATION, EVALUATION CRITERIA AND HOW TO PREPARE ANAPPLICATION UNDER AN AREA OF INTEREST. Please scroll to the bottom of thispageto access the Funding Opportunity Announcement (FOA Master.doc).Area of Interest 4: SEALING SYSTEMS BASED ON VISCOUS GLASSObjective: The objective of this topic is to develop novel viscous sealingconcepts for SOFCs. Such concepts may offer significantly improvedlong-termstructural durability under SOFC operating conditions, particularly withrespect to accommodation of dimensional changes of cell/stack componentsresulting from thermal transients and gradients.Project Description: Seals for planar SOFCs are subject to a demanding setofimposed performance criteria due to the extreme operating environment. Theseals must prevent the mixing of fuel and oxidant streams as well aspreventreactant escape to the surrounding environment. The seals must have a lowelectrical conductivity, be chemically and mechanically stable in a hightemperature reactive environment (moist reducing and/or oxidizingconditions),and demonstrate chemical compatibility with the cell and interconnectmaterialsof the particular SOFC cell/stack design. Volatile constituents (e.g.,alkalis) in the seal should not have a deleterious effect upon cathodeperformance. Of particular importance is the ability to seal materials(e.g.interconnect alloys, Ni-YSZ cermet anodes) with differing coefficients ofthermal expansion (CTE), and do so while exposed to temperature transientsovera range from room temperature up to the maximum SOFC operating temperature(~850�C). In addition, the seals must accommodate the thermal expansion ofthefuel cell caused by in-plane temperature gradients, the result of heatgenerated by the electrochemical reaction and removed by the cathodeairflow,without imposing excessive stresses within the cell. Fuel leakage shouldbeless than one percent (1%) for the duration of the seal life. The sealmaterial must be capable of a service life of more than 40,000 hours anddozensof thermal cycles for stationary systems. Manufacturability and cost arecritical factors in meeting SECA program goals.Applications are sought for the research and development of novel viscoussealing concepts. Such concepts may offer significantly improved long-termstructural durability under SOFC operating conditions, particularly withrespect to accommodation of dimensional changes of cell/stack componentsresulting from thermal transients and gradients. These may include glassesforwhich the softening temperature is below the lower bounds of the SOFCoperatingtemperature (650C) and are resistant to devitrification. Given that such asealing material on its own may be unable to withstand the differentialpressure across the seal (up to 2 psid) or the stack bearing load, it isenvisioned that an engineered composite solution (e.g., an impregnatedceramicfelt or other structure) will be required to carry bearing loads and retaintheviscous sealing material. The ultimate objective is the development of aneconomically-practical seal material/system that can provide near-hermeticsealing under all operating conditions for the life of planar SOFC stacks.Proposed Phase I approaches should combine rigorous analysis andexperimentation to characterize the chemical compatibility and stability ofthesealing materials in the SOFC environment, as well as composite seal designandexperimental validation. Phase II will entail larger-scale testing,potentially in partnership with other SECA Core Technology seal R D effortsorone or more SECA Industry Teams.Award Value: DOE anticipates that awards will be $300,000 for Phase I($250,000DOE Share and at least 20% Cost Share) and $300,000 for Phase II ($250,000DOEShare and at least 20% Cost Share).Interested parties looking to submit an application under this area ofinterestcan download the application package at the following link:http://apply.grants.gov/apply/UpdateOffer?id=9967
