I was learning on the stimulation of PEM Fuel Cell with the ANSYS Fluent. However, ANSYS didnt calculate the stimulation at all (didnt come out the graph and within a while show the message calculation complete). Kindly provide any useful ideas and advise on the problem, much thanks. And anyone could kindly share me the ANSYS PEM Fuel Cell stimulation tutorials?

Hello,

There are a number of tutorials on YouTube which show how to model PEM fuel cell on Ansys Fluent. Here is one such 'how to' video. Please feel free to explore more on YouTube.

Thank you.

thanks

Is the mesh imported in the tutorial provided somewhere? Do I have to create it myself?

There isn't a copy in the Help system so I suspect you'll need to create it yourself.  If you open Fluent are there any errors when you try and run the model?

I made a model, created a mesh and tried to calculate it, but when I initialize it, the following error occurs.

---

Internal error at line 5527 in file 'win643ddp_nodepemfc.c' on Node 0.

inquire_stack_voltage_bc_types: Unknown bc type

Internal error at line 5495 in file 'win643ddp_nodepemfc.c' on Node 0.

I'm not sure about this error. I think that the setting of PEMFC model or the setting of boundary conditions is incorrect.

It would be helpful if you could give me your opinion.

The mesh won't help, but yes, it looks like you missed something in the fuel cell model.

hi,nwhen i run the pemfc model, i followed all the steps by tutorial and boundary conditions also once twice i checked everything is correct. but whenever running file i am getting error like above shown in figure and error:mpt666 error exites, amg species: error, fatal error. Like this error only i am getting everytime. My mesh skewness value is .73 only. I tried it so many times to run the file but everytime hitting some error like this. My pc configuration is i5, 16gb ram, 4gb gtx1650 graphic card nvidia, 256gb ssd, 1tb hdd. What is meaning error mpt: error means? Floating point exception error.nn
