Ni foam substrate
Porous 130 ppi substrate
Who it is for
An anode that stays constant while you change membranes or cells
HXP-an is an OER anode with NiFe LDH grown directly on a Ni foam substrate. Review the material architecture, standard formats and test conditions before selecting the size for your study.
Choose this product when
- Development aiming to lower AEM electrolysis anode cost with NiFe-LDH on nickel foam
- Research evaluating a NiFe-LDH OER anode in a single cell or short stack
- MEA fabrication or electrode cutting that needs a standard or custom-size anode
FROM MATERIAL TO ELECTRODE
How the NiFe LDH anode is built
The OER anode is made by growing a NiFe LDH catalyst layer directly on a porous Ni foam substrate. It contains no platinum-group metal and no iridium. Because the catalyst is grown on the substrate itself, HXP-an is supplied as a catalyst-coated substrate (CCS) electrode rather than a catalyst-coated membrane (CCM).

Support, lead time and commercial terms3 items
Replacement & technical support
The anode uses our own synthesized NiFe-LDH, so replacements to the same specification come directly from us. We sign an NDA where detailed performance data or test results need to be exchanged.
Lead time & status
Available · 2 weeks from PO acceptance for standard formats (custom up to 2 months)
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.
