Spatial harmonic current density basis for faults identification in fuel cell stack from external magnetic field measurements

Résumé

An original approach used for the identification of faults in fuel cell stacks is presented. It is based on the 3D reconstruction of the current density from external magnetic field measurements which is an ill-posed magnetostatic linear inverse problem. Suitable current density and magnetic field basis are proposed in order to define both local and global faults on a fuel cell stack. In order to ensure the uniqueness of the solution, the inverse problem is regularized thanks to the truncated singular value decomposition (SVD).
