Product Overview

This high-performance modular electrochemical stack cell utilizes an advanced bipolar stacking architecture to enable scalable high-voltage and high-power laboratory research. By configuring individual flow field plates with distinct cathode and anode faces, this system minimizes external wiring and ohmic losses, delivering exceptional electrical efficiency across the entire assembly.

The equipment is optimized for critical green energy applications, including carbon dioxide reduction, water electrolysis, and organic electrosynthesis. It serves as a highly adaptable testing platform for clean energy laboratories and chemical research institutes worldwide.

Constructed from high-purity titanium, the unit ensures outstanding chemical resistance under aggressive experimental conditions. Its advanced clamping design guarantees uniform mechanical force distribution, ensuring long-term reliability and reproducible testing results.

Key Features

• Modular Stacked Architecture: This advanced system utilizes individual flow field plates designed for modular stacking, allowing researchers to scale operating voltages and power capacities easily. By employing a bipolar design where a single metal plate functions as both the cathode and anode, the unit significantly reduces internal resistance, optimizes electrical current paths, and simplifies stack assembly for high-throughput experiments. This modularity means that a single purchase can support a wide variety of configurations, from basic two-electrode research to highly complex multi-stage pilot-scale processes.
• Premium High-Purity Metallurgy: The primary components are precision-machined from high-purity titanium, delivering exceptional resistance to mechanical stress and electrochemical corrosion. For highly specialized or extreme environments, such as highly alkaline water electrolysis, the option to equip the cell with high-purity nickel plates is available, ensuring compatibility with virtually any reaction chemistry. This carefully chosen material profile prevents the introduction of trace metal impurities into the electrolyte, preserving the integrity of sensitive catalytic evaluations.
• Customizable Flow Field Geometries: To support diverse mass transport and fluid dynamics investigations, the cell is compatible with multiple standard flow field designs including serpentine, parallel, and vein-type patterns. Additionally, KINTEK's advanced custom manufacturing capabilities allow for the integration of specialized spiral, mesh, and comb-type channels to match specific reactant flow requirements. This level of customization enables researchers to accurately mimic industrial-scale flow dynamics and optimize hydrodynamic parameters within a benchtop laboratory setup.
• Precision Temperature and Thermal Control: Designed to facilitate isothermal electrochemical testing, the reaction cell is engineered with integrated heating element ports and high-precision temperature measurement wells. This thermal configuration allows researchers to maintain stable operating temperatures, evaluate activation kinetics, and accurately measure thermodynamic performance under controlled thermal states. The integrated ports are situated close to the active reaction area, ensuring fast thermal response times and minimized temperature gradients across the stack.
• Dual Flow Path Interconnection Modes: To accommodate varying research methodologies and fluidic designs, the flow channels between adjacent plates support both series and parallel fluidic routing. This configuration flexibility enables users to optimize fluid residence time, balance pressure drops across the stack, and manage reactant depletion profiles to match specific process requirements. Researchers can quickly reconfigure the plumbing layout externally, allowing for swift comparative studies between different fluidic operating modes.
• Uniform Clamping Force Distribution: The structural fastening system is engineered to apply exceptionally uniform mechanical pressure across all stacked plates. This precise pressure distribution eliminates localized current crowding, minimizes interfacial contact resistance between components, and guarantees a completely leak-free seal across the entire stack assembly during high-pressure operation. By preventing uneven mechanical stress, the cell design also extends the operating lifetime of delicate membrane electrode assemblies.
• High-Performance Current Collection: Equipped with premium gold-plated copper current collectors, the cell ensures maximum electrical conductivity and minimal contact resistance at the stack terminals. The gold-plated layer provides superior protection against surface oxidation and chemical degradation, guaranteeing stable long-term electrical connections and high-accuracy data acquisition. This high-efficiency current collection design ensures that all measured overpotentials are directly attributable to the electrochemical reaction rather than system contact resistance.
• Advanced Chemical-Resistant Sealing: High-elasticity silicone gaskets are utilized between every stacked component to ensure robust fluidic isolation and leak-proof performance. These gaskets are selected for their excellent thermal stability and broad chemical compatibility, preventing electrolyte leakage and cross-contamination between the anode and cathode flow chambers. The high mechanical resilience of the silicone ensures that the seals retain their elastomeric properties even after multiple assembly and disassembly cycles.

Applications

Technical Specifications

The PL-DJ30 electrochemical stack cell is engineered to meet precise dimensional and material standards, ensuring consistent performance across all custom configurations. The core architecture relies on high-precision machined plates that maintain strict parallel tolerances, ensuring optimal electrical contact and fluidic isolation. Below is the detailed breakdown of the technical specifications, physical properties, and material composition of the system.

Flow Field Geometry and Fluid Dynamics

The fluidic performance of the PL-DJ30 is highly dependent on the choice of flow channel geometry. Serpentine channels are optimized for high gaseous reactant flow, forcing reactants across the catalytic surface to maximize mass transport, which is highly beneficial for carbon dioxide reduction. Parallel channels are designed to minimize pressure drops, making them ideal for high-flow-rate liquid electrolytes in redox flow battery applications. Vein-type (leaf-vein) flow fields offer a balanced distribution profile that mimics natural fluidic networks, ensuring uniform reactant distribution with minimal mechanical stress on the integrated membranes.
