Overview

OPEM is an open source PEM cell simulation tool

Installation

Source Code

• Download Version 0.1 or Latest Source
• Run pip install -r requirements.txt or pip3 install -r requirements.txt (Need root access)
• Run python3 setup.py install or python setup.py install (Need root access)

PyPI

• Run pip install opem or pip3 install opem (Need root access)

Usage

CLI (Command Line Interface)

• Open CMD (Windows) or Terminal (UNIX)
• Run python -m opem or python3 -m opem
• Enter PEM cell parameters
  • T : Cell Operation Temperature [K]
  • PH2 : Partial Pressure [atm]
  • PO2 : Partial Pressure [atm]
  • i-start : Cell load current start point [A]
  • i-step : Cell load current step
  • i-stop : Cell load current end point [A]
  • A : active area [cm2]
  • l : Membrane Thickness [cm]
  • lambda : is an adjustable parameter with a possible maximum value of 23
  • R : R-Electronic [ohm] (*Optional)
  • B : Tafel Slope
  • JMax : maximum current density [A/cm2]
  • N : Number Of Single Cells
• Find Your Result In Simulation-Result.opem file (Open with Notepad)
