Abstract This work presents comprehensive studies of inlet gas humidification on O2 mass transport and proton exchange membrane fuel cell performance to obtain a better understanding of transport processes at a cathode gas diffusion electrode. The O2

The work presents a model for local impedance of low-Pt proton exchange membrane fuel cells (PEMFCs), including cathode pore size distribution and O2 transport along pores and through a thin ionomer film covering Pt/C agglomerates. The model was appl

The complex operating behaviour of PEM Fuel Cells is heavily influenced by different non-linear loss processes, which limit the cell performance. Depending on the operating conditions, the different losses change in magnitude and characteristic time

We report analysis of a recent model for local current density distribution along the air channel in a PEM fuel cell. Analytical solution for the case of small cell ohmic resistivity is obtained. An algorithm for numerical solution of the model equat

Measured impedance spectra of a low–Pt PEM fuel cell exhibit high slope in the high–frequency range. To explain this feature, we introduce an "external" capacitance Cext connected in parallel to our recent model for the cathode catalyst layer imp

Unexpected over-linear transport loss in low-Pt PEM fuel cells has been a subject of numerous studies and discussions in literature. Most of the authors agree that these losses are due to oxygen transport in the Nafion film covering Pt/C agglomerates

Distribution of relaxation times (DRT) is calculated from fifty local impedance spectra of a low–Pt PEM fuel cell. 48 out of 50 DRT spectra contain three peaks. Evolution of the peak frequency positions and resistivities with the cell current densi

A new platinum group metal (PGM)-free proton exchange membrane fuel cell (PEMFC) cathode catalyst materials, synthesized using the VariPore™ method by Pajarito Powder, LLC, are characterized for their structure and activity. The physico-chemical an
