but.defenceThe student presented his final thesis and answered the questions posed by the opponent. In the subsequent discussion regarding the diploma thesis, he addressed questions from the committee members: - Prof. Novotny - Your work is about mathematical modeling, but I cannot see any model in your presentation. Can you please present (describe) your model in more detail, and describe the equations used? - Prof. Novotný asked about the inputs for the model developed . - Assoc. Prof. Charvát – What does 'advance' mean in your thesis topic? What does 'enhance' refer to in your model? - Assoc. Prof. Jan – On slide 11, you showed the value of mean absolute error 0.6767 V. What does this mean? Is it physically viable? What is the accuracy of the measurement? - Assoc. Prof. Jan - Are there any other options to store and transport hydrogen except the gas state you mentioned? - Assoc. Prof. Lízal - Why did you validate your model with 'model' data and not use experimental data? - Assoc. Prof. Lízal - You mentioned you tuned the model to achieve better precision. How was this realized? - Assoc. Prof. Šremr - How did you get the graph on slide 7? Can you describe the procedure? - Assoc. Prof. Charvat - Did you try to compare your model with models available from the MATLAB community? The student's responses did not provide the required depth/clarity.cs

dc.description.abstractThis thesis presents a zerodimensional proton exchange membrane fuel cell (PEMFC) model tailored for controloriented and systemlevel simulations. The boundary conditions were considered on the stack inlets and the key parameters such as membrane resistance, exchange current density, and reactant flow rates were calibrated against published data, and a singleparameter leastsquares tuning coefficient was applied to align the model’s voltagecurrent characteristics with a benchmark, yielding a Mean Absolute Error of 0.6767 V and a Mean Relative Error of 1.45 %. Stack power and efficiency curves were analyzed across the current sweep, including visualizations of voltage, current, and power, demonstrating numerical stability and predictive accuracy. The results confirm that the integrated thermal, electrochemical, masstransport, and hydration dynamics produce a robust tool for preliminary PEMFC design and control studies. Future work will involve validating the model’s predictions against detailed experimental polarization, transient, thermal management, and hydration data to further refine parameters and support realworld hardware integration.en
