Hydrogen polymer electrolyte membrane (PEM) fuel cells use hydrogen and oxygen to produce electricity through an electrochemical reaction. Fuel cells consist of an anode, cathode, and electrolyte membrane.
A hydrogen PEM fuel cell produces electricity without combustion. The only byproduct is water and heat, making it a very clean electric energy source.Monarch hydraulic Lab Press. Image Credit: Carver, Inc
Since hydrogen PEM fuel cells are a source of clean energy, they are suitable for applications in environments not conducive to hydrocarbon emissions. In addition, PEM fuel cells can be used continuously in applications where you cannot have downtime, unlike EV batteries that need to be recharged.
Presses are used to laminate the PEM Fuel cell components together. This requires a press with heated platens (less than 500 deg F) and clamp forces that apply up to 150 PSI on the laminate.
Presses can be as simple as a hand-operated model for R&D applications or multi-opening presses with load and unload capabilities for full-scale PEM fuel cell production.
Selecting the proper tonnage and platen size is essential. The platen area should be large enough to allow a perimeter around the laminate for uniform heating.
Virtually any heated presses Carver offers could be used for PEM fuel cell laminating. The line is wide-ranging in tonnage and platen size, with several manually operated and semi-automated presses available.
Presses offer a cost-effective method for laminating PEM fuel cells as they are relatively inexpensive. In addition, presses are easy to operate, consistent, and reliable.
As the hydrogen energy market grows, there will be an increased need for quicker means of laminate PEM fuel cells. Automated systems will continue to be developed to provide the necessary capacity for the expected future demand as technology acceptance grows.
