Membrane Electrode Assembly (MEA) Activation Procedures

Why is an activation procedure or break-in necessary for a membrane electrode assembly (MEA)?  A large reason for performing an activation procedure or break-in is to properly humidify the membrane portion of the MEA that was dried out during the hot press stage of the membrane electrode assembly (MEA) production.  MEAs will not work well when they are not fully humidified (see article: Why is Humidity / Moisture Control Important in a Fuel Cell?).How do I Humidify a Membrane Electrode … [Read more...]

FuelCellsEtc Develops Custom Pricing Calculator

FuelCellsEtc has released an online pricing tool that gives users instant price quotes for custom 5 – Layer or single sided Membrane Electrode Assemblies (MEAs).  This marks the first time such a tool has been made available to the fuel cell industry.The tool allows the user to customize sizing, catalyst configuration, and membrane type, with dynamically updated pricing, and the ability to immediately purchase their custom product online.  FuelCellsEtc notes that there … [Read more...]

Does FuelCellsEtc Provide Hydrogen Generators (or HHO) for Cars?

The short answer is no, we do not.  At this time we do not have any kits or systems designed to generate Hydrogen on-board for vehicles.  However, a quick Google search for HHOs brings up numerous kits and system suppliers. However if you are looking in to building an HHO generator yourself, we do recommend taking a look at our Electrolyzer Membrane Electrode Assemblies (EZ MEAs). Our EZ MEAs are very efficient (far more efficient than a standard SS metal electrode) but certainly … [Read more...]

What Nafion Membrane Thickness is Right for an Electrolyzer / Hydrogen Generation?

Nafion membranes come in many different thickness and types.  How do you know which to choose when designing an electrolyzer (hydrogen generator)?Choosing the proper thickness depends primarily on the differential pressure you expect across the membrane (i.e. what pressure you will be generating the hydrogen at vs. the oxygen), the type of support the membrane will have, and the operating lifetime (both hours and on/off cycles). Our Standard … [Read more...]
