Determination of the optimal design of experiments that enables efficient parametrisationof fuel cell (FC) model with a minimum parametrisation data-set is one of the key pre-requisites for minimizing costs and effort of the parametrisation procedure. To efficientlytackle this challenge, the paper present an innovative methodology based on the electro-chemical FC model, parameter sensitivity analysis and application of D-optimal designplan. Relying on this consistent methodological basis the paper answers fundamentalquestions: a) on a minimum required data-set to optimally parametrise the FC model andb) on the impact of reduced space of operational points on identifiability of individualcalibration parameters. Results reveal that application of D-optimal DoE enablesenhancement of calibration parameters information resulting in up to order of magnitudelower relative standard errors on smaller data-sets. In addition, it was shown thatincreased information and thus identifiability, inherently leads to improved robustness ofthe FC electrochemical model.
