Project Description

Accumentrics will team with the National Renewable Energy Laboratory (NREL), under separate field work proposal FWP-HYW1052A, to improve solid oxide fuel cell (SOFC) system reliability. Non-destructive and automatable techniques will be developed for identifying defective SOFC cells prior to stack and system assembly, thereby improving quality control and long-term performance by preventing premature stack failure (see Figure 1). High-speed methods for defect detection and an understanding of the type of defect and its effect on degradation will be established to progress towards commercially viable production rates.

Project Benefits

This Acumentrics project will decrease life cycle cost by improving stack mean time to failure and by identifying and rejecting defective cells before assembly. Production cost will be reduced by using advanced quality control concepts, high-throughput machine vision based instruments for automatic quality control, and rejecting cells only if their imperfections are known to be correlated with increased degradation or performance loss.
