Abstract

The influence of hindered water removal from a polymer electrolyte fuel cell under constant load was investigated using electrochemical impedance spectroscopy. The cathodic gas outlet of the cell was closed and impedance measurements were performed at periodic time intervals. Under the experimental conditions, the investigated system is far from steady-state conditions. It is shown that enhanced mathematical techniques are required for evaluation of the impedance data obtained. These techniques, the time course interpolation as well as the Z-HIT refinement, lead to quasi-causal spectra which are well interpreted by means of the porous electrode model.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
