Acoustical Characteristics of Proton Exchange Membrane Fuel Cells [PDF]

IEEE Access, 2021
In order to optimise the performance of Proton Exchange Membrane Fuel Cells (PEMFCs) and to maximise their life cycle, water content has to be properly controlled. This paper presents a model-based method to determine the effect of load on PEMFC water content in PEMFCs using Acoustic Emission (AE) measurements.

Assembly techniques for proton exchange membrane fuel cell stack: A literature review

, 2022
The assembly of proton exchange membrane fuel cell (PEMFC) is a complex process. The joint action of the assembly load and the working temperature causes an uneven stress distribution among the components and produces a certain degree of deformation.
