Powering Fuel Cells with Nafion™ Membranes

Fuel Cells Power a Safer and Cleaner World

Fuel cells are electrochemical cells that convert chemical energy from a fuel—typically hydrogen and oxygen—into electricity through an electrochemical reaction. They complement many green energy efforts and are key enablers for providing clean energy at any scale.

International regulations mandating significant reductions in global warming emissions make the adoption of fuel cells ever-more critical. The global fuel cell market is expected to grow at a compound annual growth rate (CAGR) of 20.9% through 2025[1] across a broad range of use cases, including:

  • Power sources in light electric, hybrid, heavy transport, and material handling vehicles
  • Back-up power for buildings
  • Off-grid power for applications like telecom stations
  • Mega-watt sized back-up or off-grid power systems for industrial plants or municipalities

The common characteristic in all use cases is the need for an ion exchange membrane that offers durability and performance. Nafion™ proton exchange membranes (PEM) meet this need.


Improve Conductivity and Increase Durability with Proton Exchange Membranes

Nafion™ membranes can build fuel cells that run efficiently for years. Engineers and designers specify Nafion™ PEMs for their fuel cells because of their:

  • Thickness
  • Conductivity
  • Strength
  • Resistance to water uptake
  • Chemical durability

These properties can be leveraged to meet the requirements of new designs and operating conditions. Specifically, fuel cells that use Nafion™ PEMs:

  • Work well with intermittent renewable energy from solar or wind
  • Operate at relatively low temperatures
  • Tailor electrical output to meet dynamic power requirements

As a result, fuel cells using PEMs are viewed as the leading technology for light-duty vehicles and many stationary applications.
