The effect of in-phase current and temperature oscillations on the impedance of the cathode catalyst layer in a PEM fuel cell
Andrei Kulikovsky
An impedance model for the cathode catalyst layer (CCL) in a PEM fuel cell demonstrates that in-phase harmonic perturbations to the cell current density and CCL temperature lower b…
In-phase current and temperature oscillations reduce PEM fuel cell resistivity: A modeling study
Andrei Kulikovsky
We have developed a non-isothermal analytical model for the impedance of the cathode catalyst layer (CCL) in a PEM fuel cell. In-phase harmonic perturbations to the current density…
A model for water transport in the membrane and an impedance spectroscopy study of the effect of relative humidity on PEM fuel cell parameters
Andrei Kulikovsky, Tatyana Reshetenko
Effective water management is essential for the optimal performance of PEM fuel cells. We have developed an impedance model for liquid water transport through the membrane and coup…
Impedance of a hydrogen--fed SOFC anode: Analytical and numerical models based on the dusty gas transport model
Andrei Kulikovsky
Analytical low-current and numerical high--current models for the impedance of a hydrogen--fed anode of an anode--supported button SOFC are developed. The models use the dusty gas…
