About the PEM Fuel Cell Process

Hydrogen gas is oxidized within a fuel cell. In theprocess, the chemical energy stored in the hydrogen gas is converted directly,i.e. without combustion, to electrical energy. This process takes placein the heart of the fuel cell, the Membrane Electrode Assembly (MEA).

The MEA comprises two electrodes (cathode: oxygen sideand anode: hydrogen side) and the Proton Exchange Membrane (PEM). The PEMis a special plastic film which is permeable to protons but which presents abarrier to electrons.

Hydrogen gas is split by catalysis into electrons andprotons in the fuel cell. Due to the chemical imbalance created, theprotons (cations) diffuse through the PEM. The resulting potentialdifference can be tapped on the electrodes in the form of a no-load voltage. As soon as an electric circuit is connected to the fuel cell, the surpluselectrodes flow to the cathode, where they combine with the oxygen and theprotons to form water (H₂O). The water produced escapes viathe air vent in the form of water vapor.

FAQs of Fuel Cell Stack 3:

Q: How do I operate the Fuel Cell Stack 3 safely in a laboratory setting?

A: Ensure hydrogen (H2) and ambient air (O2) are supplied at appropriate flow rates and concentrations. Use 3 mm barbed fittings for gas connections, verify seals with PTFE or silicone O-rings, and maintain the stack within a 20C to 60C operating range. Adequate external humidification should be provided to maintain optimal cell performance.

Q: What applications is the Fuel Cell Stack 3 best suited for?

A: This stack is specifically engineered for research, laboratory experiments, and educational demonstrations. It is ideal for universities, research institutions, and demonstration setups thanks to its robust mechanical integrity, moderate power output, and straightforward integration.

Q: When is external humidification required, and why is it important?

A: External humidification should always be used when operating this stack to prevent membrane dehydration, which can reduce efficiency and performance. Controlled humidity ensures consistent electrochemical reactions within the stack, promoting longevity and reliable output.

Q: Where can I purchase or source the Fuel Cell Stack 3 in the United States?

A: The Fuel Cell Stack 3 is available through authorized distributors, manufacturers, suppliers, retailers, and traders throughout the United States. Reach out to these channels for product availability, technical support, and purchasing information.

Q: What is the process for connecting and supplying gas to the fuel cell stack?

A: Connect hydrogen and ambient air/oxygen sources using the built-in barbed fittings for 3 mm tubing. Ensure all connections are securely clamped and sealed with PTFE or silicone O-rings/gaskets. Always use hydrogen of at least 99.99% purity for optimal performance.

Q: How does the Fuel Cell Stack 3 benefit research and educational environments?

A: Its compact form, bolt-clamped modularity, and high-purity construction facilitate clear demonstration of PEM fuel cell principles and hands-on experimentation, making it a valuable tool for evolving research and engaging classroom instruction.
