Dear Sir/Madam,
We are a hydrogen fuel cell research team from the School of Automotive and Energy Engineering, Tongji University, Shanghai, China. We are investigating the use of low-temperature gas media at 100K–150K as an alternative to traditional coolants for heat exchange in fuel cells.
We intend to perform simulations using the PEMFC module in ANSYS FLUENT and design physical experiments for validation. However, we have encountered an uncertain issue:
When using low-temperature gas at 70K for heat exchange, the catalyst layer temperature gradually transitions from 180K to 300K, and non-negligible current density still exists in the subzero low-temperature region.
We would like to inquire whether, in the underlying logic of the FLUENT PEMFC module, the validity and accuracy of electrochemical equations at subzero temperatures have been considered, and whether the reactions can proceed smoothly under such conditions, or if there is an alternative explanation.
If these scenarios are not currently accounted for, would your company be interested in conducting joint research with our team to further explore this issue?
Thank you very much for your time and consideration.
