Active area
Select 1–25 cm² through the gasket window
Is this the right product?
Can my MEA and test equipment support the evaluation I need?
HXS-0 sets active area through the gasket window and scales from a single cell to a short stack. The key is to define the boundary between cell hardware, MEA and your power and circulation equipment.
Choose this product when
- Research screening catalyst, membrane and electrode combinations at cell level
- Defining scale-up conditions from single cell to short stack
- Comparing performance with MEAs you fabricate yourself
Product and supply boundary
Define the test through four configuration choices
Set the active area, cell count, MEA and available test equipment to define the required hardware.
Cell count
Single cell to 20-cell short stack
MEA and electrodes
Own or third-party MEA, or HXP electrodes
Test station
Power, circulation, temperature control and data logging
Included supply scope
- Selectable 1–25 cm² active area, from a single cell to a 20-cell short stack
- SUS316L end plates, nickel-based bipolar plates, PTFE gaskets and a single-serpentine flow field
- MEA excluded as standard · MEA with HXP-an, HXP-ca and membrane available on request
Customer preparation
- Power supply (a programmable unit is recommended for wide voltage and current sweeps)
- Electrolyte circulation, temperature control and data logging
- MEA or electrodes (our HXP-an and HXP-ca can be used)
