In this tech talk, Steven had the pleasure of discussing Hydrogen Fuel Cell Stack Design with Roger Penn, Senior Engineer at AVL Fuel Cell Canada.
Learn about Hydrogen Fuel Cell Stack Design
Steven Oji and Roger Penn discussed the technology behind the hydrogen economy, focusing on fuel cell stacks. The factors that influence stack design are such as power, heat rejection, efficiency, voltage, and packaging space, as well as shock and vibration. In terms of shock resistance, rail applications have the harshest requirements. Roger also discussed the difference between fuel cell stacks used in marine, automotive and rail applications. The need to match the stack voltage to the DC DC converter and the importance of ensuring the stack can handle shock and vibration were also outlined.
The topics such as converter voltage and shock and vibration were also discussed. Roger explains that when designing a fuel cell stack, factors like heat rejection, efficiency requirements, active area, current density, packaging space, voltage, DC-DC converter, compression force, shock, and vibration are all interrelated, and the designer must take into consideration all these inputs from the requirements and the customer to decide the number of cells that are required in the stack.
