PEM Stack Modules

Find and compare PEM stack modules from leading B2B suppliers with technical specifications. PEM (Proton Exchange Membrane) stack modules are the core energy conversion units in low-temperature fuel cell systems, converting hydrogen into electricity through an electrochemical reaction. These modules are widely used across the hydrogen industry in mobile, stationary, and portable power applications — from hydrogen-powered vehicles and backup power units to electrolyzers and distributed energy systems. PEM stack modules are known for their compact size, high power density, fast startup, and low operating temperatures (typically 60–80 °C). When selecting a PEM stack module for hydrogen applications, important considerations include rated power, number of cells, voltage output, cooling method (air or liquid), and integration compatibility with the overall fuel cell system.
