An open-source modeling tool for evaluating the performance of proton-exchange membrane fuel cells (PEMFC) using static and dynamic models.
OPEM is an open-source simulation tool for modeling and evaluating the performance of proton-exchange membrane fuel cells (PEMFC). It combines multiple static and dynamic models to predict optimal operating parameters, helping researchers and engineers analyze fuel cell behavior under various conditions. The tool addresses the need for accessible, collaborative platforms in renewable energy research.
Researchers, engineers, and students working on fuel cell technology, renewable energy systems, and electrochemical modeling. It is particularly useful for those developing or validating PEMFC models in academic or industrial settings.
Developers choose OPEM because it provides a comprehensive, open-source collection of validated PEMFC models in one package, supports multiple interfaces (library, CLI, web), and fosters collaboration through its platform approach, unlike proprietary or single-model solutions.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Integrates eight established static and dynamic models like Amphlett, Padulles, and Chakraborty, providing a comprehensive toolkit for PEMFC analysis without needing separate implementations.
Offers a Python library, command-line executable, Telegram bot, and Jupyter Notebooks via Binder, allowing users to choose their preferred interface for simulation and prototyping.
Generates performance metrics (e.g., voltage, power, efficiency) and losses in HTML, CSV, and custom .opem formats, facilitating easy data export and integration into research documentation.
Designed as a collaborative platform with clear contribution guidelines and Discord support, encouraging community-driven development and validation of PEMFC models.
Each model demands numerous specific inputs with precise units (e.g., valve constants in kmol.s⁻¹.atm⁻¹), which can be daunting for users without deep fuel cell expertise.
Exclusively focuses on proton-exchange membrane fuel cells, lacking support for other fuel cell types like solid oxide, reducing its utility for broader electrochemical research.
Relies on static report formats or external tools for data visualization; there's no interactive graphical interface for real-time plotting or model tweaking within the core package.
