Ballard Mark-700 75kW Fuel Cell Simulink Model

This document presents a Simulink model of a fuel cell system. The model is developed based on the Ballard Mark-700 75kW fuel cell prototype. Fuel cells represent advanced energy technology that converts hydrogen and oxygen into electrical energy while producing water as a byproduct. Simulink provides a graphical environment for modeling and simulating dynamic systems, enabling comprehensive analysis of fuel cell operational principles and performance characteristics through block-based system representation.

First, let's examine the key features of the Ballard Mark-700 75kW fuel cell. This prototype, developed by Ballard Power Systems, delivers 75 kilowatts of power output. It represents a high-efficiency, reliable, and stable fuel cell system widely implemented in automotive applications, public transportation, and industrial sectors. The model incorporates electrochemical equations and mass balance calculations to accurately represent the prototype's performance metrics.

The Simulink model construction utilizes a modular approach where each subsystem corresponds to physical components. Key blocks include hydrogen supply system modeling with flow control algorithms, oxygen/air management module with pressure regulation, membrane electrolyte assembly with proton exchange dynamics, and thermal management system with temperature control logic. These subsystems are interconnected through signal lines representing mass/energy flows, with each block containing MATLAB functions implementing electrochemical reactions and power calculation algorithms. The simulation enables parameter sweeps and transient response analysis through Simulink's solver configurations.

In summary, the Simulink modeling approach provides valuable insights into fuel cell operation mechanisms and performance optimization. This methodology significantly contributes to advancing fuel cell technology development and practical applications. The model structure allows for easy modification of operating parameters and integration with hybrid power systems through Simulink's library connections.
