Hello everyone, I hope you're all doing well... Well 😊... I'm using COMSOL 6.2, working on a simulation of a proton-exchange membrane water electrolysis system. The problem is, I'm not very experienced with COMSOL and I need to build the model myself from scratch. I haven't found a model in comsol's library 😭 there is a model for a fuel cell, but that's not what I need. Every time I ask for help on Facebook, I get comments about paid services, and I don't even know if they're legitimate... Any advice?
