The PEM Interdigitated Fuel Cell is a high performance fuel cell stack with a new separator plate design giving a highly efficient reactant transport, and with a careful connector design providing corrosion resistance. The stack is built with robust quality and durability allowing for repeated assembly and dis-assembly. The new separator plate includes an interdigitated flow field design, so that reactant is forced through the porous gas diffusion layer (GDL). The forced flow helps to transport reactant to the reactive catalyst layer thus reducing mass transfer limitation and increase power output. The fuel connection is specifically designed and made with a direct connection between the graphite separator plate and Nylon (or Teflon) fittings, so that fuel and the current collector and end plate do not come in contact, making them corrosive resistant. The stack with the interdigitated plate is available in 50 cm². A cooling plate is also available for the 50 cm² stack.

Fumasep FBM Bipolar Exchange Membrane with PK reinforcement consists of an anion exchange layer and a cation exchange layer manufactured using a patented multilayer-coating production technology. This composite membrane is chemically stable and mechanically reinforced with woven PEEK. In the intermediate layer between Anion Exchange Layer (AEM) and Cation Exchange Layer (CEM) water is catalytically active to force dissociation of water into OH- and H+ – ions when exceeding a potential difference of approximately 0.8 V. The membrane should be operated under forward bias conditions which may cause blistering. The CEM must be directed towards the cathode, the AEM must be directed towards the anode. If the membrane is used in the wrong position at high current density even for short term, the interim layer may degrade (blistering), and the monolayers may delaminate.

The AEM Water Electrolyzer is a complete alkaline anion exchange membrane water electrolyzer hardware. The hardware includes corrosion resistant 5 cm² Nickel anode and cathode flow fields, an MEA with base metal catalysts, metal gas diffusion layers, o-ring seals, and Teflon gasketing. Please note that there are no heaters or cables included. The electrolyzer is designed to be run with 1 M KOH flowing on the anode and cathode as described in Zengcai Liu et al. “The effect of membrane on an alkaline water electrolyzer”.

Building on the strong history of PEM fuel cell research and test data using 50cm² cells, the Expandable PEM Research Cell is a robust development tool using well established materials, techniques and quick assembly features. These features make it ideally suited for sample screening, research and development, and educational purposes. As a short stack, it is ideal for advanced system testing.

Fuel Cell Hardware is an electrochemical device that converts chemical fuel, such as hydrogen, natural gas, methanol, etc. into energy and water. This item includes all the key components to make such reactions occur. It also performs compression of the membrane electrode assembly (MEA) while providing uniform gas distribution and uniform temperature to the cell. A gold-plated plate serves as current collector plate for the fuel cell. The gold plating provides corrosion protection and good electrical contact with the graphite separator plate. A high purity graphite plate with high electrical conductivity (900 Scm-1) and high thermal conductivity (117 Wm-1K-1) is designed with gas flow channels and manifold. A Gasket is included to provide a secured seal for the MEA. High power silicon rubber heaters are installed at both ends of the fuel cell to maintain a constant cell temperature.

Fuel Cell Store’s Single Cell Interchangeable Test Hardware was designed by one of the leading companies in electrochemical research and development to be one of the highest quality and most flexible test fixtures on the market. The test fixture is custom machined from stainless steel to provide flat, even compression across the entire face of your test MEA. The plates are gold plated for maximum conductivity to alleviate parasitic contact losses during your testing. The endplates are pre-drilled for 3/16” cartridge heaters (2 per endplate), or they also have a single pass port, on each endplate, for water to circulate to control the temperature via an external temperature bath. To read the temperature of the cell, each endplate has a 1/8” smooth thermocouple port and an 8-32 tapped port for a surface mount temperature sensor.

Nafion™ Membrane is used to separate the anode and cathode compartment of Proton Exchange Membrane fuel cells and water electrolyzers. The thickness of this particular cation exchange membrane, Nafion™ 212 makes it suitable for many Hydrogen Air/Oxygen Fuel Cell applications. Nafion™ 212 is 50.8 micrometers (2 mil) thick. The membrane is positioned between a backing film and a coversheet. Chemours (formerly DuPont) Nafion™ PFSA NR-212 membranes are based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form, and exhibit substantially lower fluoride ion release compared to the non-stabilized polymer – a sign of improved chemical durability. Nafion™ PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.

Fumasep FAS-PET-75 is a PET reinforced Anion Exchange Membrane (AEM) with low resistance, high selectivity, high mechanical stability, and high stability in pH neutral and acidic environments.

Fumasep FAS-PET-75 membrane comes in either a 10cm x 10cm or 20cm x 30cm size sheet that is delivered in a dry brown-foil form.

Fumatech membranes are highly sensitive to differences in humidity and moisture content. Therefore the membranes can vary +/- 0.5cm from the original cut sizes. Also due to this sensitivity the manufacturer expects wrinkles to form, however soaking the membranes in deionized water will return the membranes to the full size planar state according to the manufacturer.
