Simulation methodology for Fuel Cell stacks using RVE technique

A computer-implemented method for automating generation of a representative volume elements (RVE) unit fuel cell model, comprising the steps of:

• receiving a finite element model (FEM) of a unit cell of a proton exchange membrane fuel cell (PEMFC), wherein the unit cell comprises a first bipolar plate and a second bipolar plate;
• receiving an input identifying a unit region comprising a discretization of the FE unit cell based on at least one of the group consisting of geometric features of the first and/or second bipolar plate of the unit cell, a repeated feature in the geometric features, and a region of symmetry in the geometric features;
• receiving a mesh rule corresponding to the unit region;
• and
• based on the FE unit region and the mesh rule, generating an RVE unit region corresponding to the FE unit region.
