Effects of Frame Materials and Structures on Stress Concentration of Membrane Electrode Assembly of PEMFCs
Abstract
A membrane electrode assembly (MEA) is one of the core components of proton exchange membrane fuel cells (PEMFCs) comprising a catalyst coated membrane, gas diffusion electrodes, frames, and seals. By employing a 2D finite element model the mechanical stresses in membrane caused during the cell assembly procedure are analyzed for different MEA frame materials, frame structures and contact behaviors. The stress distributions in the membrane are presented and quantified. A zone with strong nonuniform stresses in the membrane under the end edge of frame/membrane is observed. The stepped frames assembly (SFA) and the bonded contact behaviors have more uniform stress distributions than the aligned frames assembly (AFA) does. The frame materials are not the main factors affecting the stress concentration in membrane for the SFA, while for the AFA the mechanical properties of frame materials should be close to those of the membrane. The results are expected to be helpful for people to select the frame materials and to design frame structures, and can be applied to guide the assembly of PEMFCs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
