AEM Water Electrolysis System – HXB-V1 (2 kW) (HXS-2 Stack + BOP)

  • HXB-V1 integrates the HXS-2 (2 kW) AEM stack with a complete Balance of Plant (BOP) to deliver turnkey, high-purity hydrogen production in a compact, plug-and-operate system.
  • Designed for labs, pilot sites, and small industrial users
  • Provides Desktop app for real-time monitoring(Dashboard), flexible control(P&ID), and automatic operation(Protocols).

Key features

  1. User-Tunable Control: Adjust key process variables (current, voltage, electrolyte temperature, electrolyte flow, etc.) freely via P&ID and automate with save/load Protocols for repeatable runs.
  2. Open-Stack Compatibility: If the bundled HXS-2 stack fails or for evaluation purposes, the system can drive a customer-supplied stack — like HXB-V1 usable like water electrolysis station testbench.
  3. High Efficiency: Optimized stack (HXS-2) and advanced electrodes (HXP-an, -ca) enable high performance.
  4. Modular & Scalable: Start with 2 kW and expand capacity by adding additional modules as needs grow.

HydroXpand Inc.

HydroXpand Inc. is a deep-tech startup focused on next-generation hydrogen production using Anion Exchange Membrane Water Electrolysis (AEMWE) technology. We develop and supply high-efficiency, durable, and cost-effective AEMWE stacks and electrodes designed for scalable green hydrogen systems.

Our flagship product is a 2kW modular AEMWE stack which can be flexibly connected to build systems ranging from hundreds of kilowatts to several megawatts. The stack operates under mild alkaline conditions and utilizes non-precious metal catalysts such as nickel and iron, providing a safe, economical, and sustainable alternative to conventional electrolysis technologies.

HydroXpand’s technology enables efficient hydrogen production for various industrial applications, including renewable energy storage, green steel, and ammonia synthesis. By overcoming the limitations of traditional electrolysis methods, we offer a scalable and competitive solution to meet the growing global demand for clean hydrogen.
