Active area
Select 1–25 cm² through the gasket window
Who it is for
A test cell built around your own MEAs and test equipment
HXS-0 is electrolyzer test cell hardware: it 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
TEST CONFIGURATION
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)

Support, lead time and commercial terms3 items
Consumables & support
Consumables such as gaskets are supplied separately, and the active area and cell count are fixed in the quotation.
Lead time & status
Available · made to order · 4 weeks after active area, cell count and flow field are fixed and the PO is accepted
Commercial terms & origin
EXW basis; DAP and other terms by agreement. Country of origin is the Republic of Korea, with certificate of origin provided.
Pricing depends on quantity and Incoterms, so it is issued as a quotation. Before asking for one, compare five years of buying cylinders against making the same hydrogen on site.
