{"product_id":"caabtfcs","title":"Flow Cell Stack for Aluminum-Air Battery Testing, CAABTFCS","description":"\u003cp\u003eTesting an Aluminum-Air (Al-air) battery presents a different set of challenges compared to hydrogen fuel cells, primarily because you are managing a solid consumable anode (Aluminum) and a liquid electrolyte (typically KOH or NaOH) rather than just gases. A flow cell stack for Al-air testing is designed to circulate the electrolyte to remove reaction byproducts—specifically aluminum hydroxide Al(OH)3—which can otherwise precipitate and \"passivate\" the anode, killing the battery's performance.\u003c\/p\u003e\n\u003cp\u003eUnlike a standard fuel cell, the Al-air stack must be designed for easy disassembly or \"mechanical recharging\" since the aluminum plates are physically consumed during discharge.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnode Compartments\u003c\/strong\u003e: (1) High-purity Aluminum (99.99%) or specific alloys (e.g., Al-Sn, Al-Ga) to reduce self-corrosion. (2) Current Collection: A brass or nickel-plated copper \"feeder\" plate presses against the back of the aluminum slab. (3) Variable Gap: Advanced test cells use a spring-loaded mechanism to push the aluminum plate forward as it thins, maintaining a constant inter-electrode distance for stable internal resistance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eElectrolyte Flow Field\u003c\/strong\u003e: (1) Manifolding: Electrolyte enters from the bottom and exits at the top to ensure gas bubbles (hydrogen from parasitic corrosion) are flushed out. (2) Turbulence Promoters: Small plastic spacers or \"mesh\" are often placed in the flow channel to increase ionic mass transfer and prevent the buildup of a stagnant boundary layer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAir Cathode (Gas Diffusion Electrode)\u003c\/strong\u003e: (1) Structure: A multi-layered GDE consisting of a catalyst layer (often Carbon\/MnO₂ or Silver), a nickel mesh current collector, and a hydrophobic PTFE layer. (2) Air Breathing vs. Forced Air: In a stack, the \"air side\" is usually a separate chamber where compressed air is lightly pressurized or fanned across the back of the cathode.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 601.226px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAABFCS (C-AABT-FCS)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 184.8px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 184.8px;\"\u003e\u003cem\u003eStructure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 184.8px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEnd\/Bipolar Plates: All-in-One Manufacturing SS316L\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFlow Channels: Serpentine (channel width: 1 mm)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eElectrode Frame: SG (0.5 mm thickness)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSealing Gasket: Silicone\u003c\/li\u003e\n\u003cli\u003eTubing Connection: Barbed hose fitting (tubing I.D. 2mm, O.D 4mm)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eM8 screw for tightening (6 pieces)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 126px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 126px;\"\u003e\u003cem\u003eCell Sizes\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 126px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eDefault effective area is 65mm * 120mm (4.0 cm2) \u003c\/li\u003e\n\u003cli\u003eOther types of active areas, such as (100mm * 120mm), are also available upon request.  \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCell size: W90×H90 mm \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 131.438px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 131.438px;\"\u003e\u003cem\u003eAssembling Diagram\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 131.438px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cp\u003e        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CAABTFCS_02_160x160.png?v=1772981342\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 84.188px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 84.188px;\"\u003e\u003cem\u003eFlow Pump (\u003cspan style=\"color: rgb(247, 8, 8);\"\u003eOptional\u003c\/span\u003e)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 84.188px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThe flow pump can be supplied upon request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e      \u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMEAFESFC_flow_pump_160x160.png?v=1772439579\" width=\"84\" height=\"69\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 39.2px;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 39.2px;\"\u003eThe cell components should be thoroughly cleaned and dried after use. \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e1. \u003ca href=\"https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/er.5485\"\u003eH.
