Stacked fixtures/reactors for membrane electrode stack cells

1Stacked fixtures/reactors for membrane electrode stack cellsCore advantages and characteristics

1. Highly simulated industrial conditions

   • adoptMembrane Electrode Assembly (MEA)Configuration, short gas, liquid, and current transmission paths, low impedance, achievableHigh current densityTesting far exceeds traditional H-type electrolytic cells, and the data has more industrial reference value.

2. goodSealing and pressure resistance performance

   • High strength and corrosion-resistant metals (such as 316 stainless steel, titanium, nickel) processed by precision CNC are used as cavity materials.

   • The combination of multi bolt uniform tightening design and high-quality sealing gaskets (such as fluororubber or PEFE) ensures that the reaction chamber is securely fastenedPositive or negative pressureCan be achieved under all conditionsbetterSealed to prevent gas crossover, ensuring experimental safety and data accuracy.

3. Modularity and high customizability

   • Sandwich style modular designStandard components include end plates, current collectors, flow field plates, sealing gaskets, etc., which can be quickly disassembled and replaced for easy cleaning, maintenance, and replacement of experimental components.

   • Flexible flow field plate optionsProvide flow field plates with various flow patterns (such as serpentine, cross finger, parallel channels, etc.), and users can flexibly choose according to the type of reactants (gas/liquid) and experimental needs to optimize the mass transfer process.

   • Compatible with multiple MEAsThe tank design is compatible with different active areas (such as 1x1)cm², 2x2cm²， 5x5 cm ², 10x10 cm ²) membrane electrodes, supporting customer made or commercialized MEA components.

4. Excellent chemical and electrochemical compatibility

   • All components in contact with the reactants are made usingHigh strength, corrosion-resistant metal materials(such as316 stainless steel, titanium, nickel, gold-plated metal plate cavitySuitable for various electrolytic environments such as acidic PEM, alkaline AEM, and neutral.

5. Integrated interface design

   • Gas/liquid import and exportConnect external devices such as mass flow meters, liquid phase pumps, back pressure valves, and gas chromatography (GC) to achieve continuous flow operation and online product analysis.

   • Temperature sensor interfaceUsed for real-time monitoring and control of reaction temperature.

   • Reference electrode interface(Optional): Reversible hydrogen electrode (RHE) can be installed to accurately measure the true potential of the working electrode.

   • Reserve standard interfaces for easy connection:

6. Accurate and reliable data

   • The symmetrical cavity design and high-precision processing technology ensure the uniform distribution of electric and flow fields, reduce edge effects, and improve test resultsHigh repeatability and strong comparabilityTo provide solid data support for publishing high-level papers and making decisions.
