Mass Flow Controllers used in PEM Fuel Cell Testing

Introduction

PEM (Proton Exchange Membrane) fuel cells have gained significant attention as a clean, efficient, and reliable energy source for various applications, including automotive, stationary power, and portable power solutions. As these fuel cells continue to evolve, the need for precise and accurate testing procedures becomes increasingly important. In this blog post, we will explore the role of mass flow controllers in PEM fuel cell testing, with a focus on the innovative solutions offered by Kelly Pneumatics. We will also discuss the importance of regulating oxidant and reactant ratios and distributions across gas diffusion layers of stacks, as well as how the use of Kelly Pneumatics Mass Flow Controllers ensures superior, reliable, and fast response times in this crucial process.

PEM Fuel Cell Testing Procedure

During PEM fuel cell testing, it is essential to simulate real-world operating conditions to accurately measure performance, durability, and efficiency. This process involves providing the fuel cell with the appropriate mixtures of hydrogen and air (or oxygen) at specific flow rates, pressures, and temperatures. The precise control of these parameters is critical in achieving optimal performance, as it ensures that the appropriate amount of reactants and oxidants are available for the electrochemical reactions taking place within the fuel cell.

Importance of Regulating Oxidant and Reactant Ratios and Distributions

To maximize the efficiency and performance of a PEM fuel cell, it is vital to maintain an optimal balance between the hydrogen (reactant) and air or oxygen (oxidant) supplied to the fuel cell stack. This balance is achieved by regulating the flow rates and pressures of the gases, which in turn affects the distribution of these gases across the gas diffusion layers within the fuel cell stack. An uneven distribution of gases can lead to localized areas of insufficient reactants or oxidants, resulting in decreased performance, lower efficiency, and potential damage to the fuel cell components.
