HXP-an PGM-free NiFe LDH anode for AEM water electrolysis

Available

Use an anode with a consistent architecture and specification for anion exchange membrane (AEM) water electrolysis while varying membranes, cells and operating conditions.

The HXP-an is a PGM-free NiFe-LDH anode electrode, available to order in two standard formats: 200 × 300 mm at 300 µm and 100 × 100 mm at 3 mm. Standard formats ship two weeks from PO acceptance; custom thickness or large areas take up to two months.

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.

Before you order

HXP-an: questions before you order

Minimum order, lead time, formats and how pricing works. The full FAQ covers operating and integration questions.

How do I buy the HXP-an?

HydroXpand sells it directly. Send the format (standard or custom size) and quantity through the enquiry form or to [email protected]; we return a quotation with price, lead time and Incoterms, and the lead time counts from the day we accept your purchase order.

Is there a minimum order quantity?

No. Standard formats can be ordered from a single sheet with no minimum order value. Before a volume order we recommend evaluating the coating and its stability on a standard 200 × 300 mm (300 µm) anode first.

What are the standard formats and the lead time?

There are two standard formats: 200 × 300 mm at 300 µm (laboratory grade, for cutting electrodes and making MEAs) and 100 × 100 mm at 3 mm (stack grade, the format used in our own stacks). Standard formats ship two weeks from PO acceptance; custom thickness or large areas (L ≤ 300 mm, W ≤ 200 mm) take up to two months because the substrate is sourced first.

How much does it cost?

Price depends on format, quantity and Incoterms, so it is issued as a quotation. The catalyst is NiFe LDH with no iridium or other platinum-group metal, so the price does not track precious-metal markets.

Under what conditions were the datasheet figures measured?

The single-electrode figures (Tafel slope 98.7 mV/dec, OER polarisation) are three-electrode measurements in 0.3 M KOH at room temperature, and the accelerated stress test is 10,000 cycles of 1.0 ↔ 0.05 A/cm² at 5 s. These differ from our stack operating condition (0.1 M KOH, 50 °C), so match the condition when you compare.

What are the commercial terms and the country of origin?

EXW is the base term and other Incoterms such as DAP are available. The country of origin is the Republic of Korea; a certificate of origin is provided, so FTA preference may apply in countries that have an FTA with Korea.
