The nest-soc package aims to help engineers and scientists to have access to state-of-art models for solid oxide cells performance and degradation.

The nest-soc package is a work in progress and this is a early preview version showcasing some use examples:

1. Polarization curve simulation for H2O-H2 operation;
2. Polarization curve simulation for syngas mixture operation;
3. Voltage degradation prediction for solid oxide fuel cell operation
4. Polarization curve simulation for CO2-CO operation and carbon formation prdiction
5. Electrochemical impedance spectrum (EIS) simulation

1. Install dependencies specified in the requirements file by running the following command (from the nest-soc root folder):

pip install -r requirements.txt

2. Run main.py file (from the nest-soc root folder):

python main.py
