Other material that you will need:
For battery:
- 2X peristaltic pump 150ml/min (you will need only one pump for semi flow battery type) Ebay or Amazon: https://www.ebay.com/itm/352994950390
- 2X glass tube 140 x 25mm (plastic tube will also be ok) Ebay or Amazon: https://www.amazon.com/Cadbibe-30ml-Plastic-Stoppers-Leak-Proof/dp/B0CLCGZ98M/ref=pd_ci_mcx_di_int_sccai_cn_d_sccl_2_2/139-5000637-7190245?pd_rd_w=AbLO8&content-id=amzn1.sym.751acc83-5c05-42d0-a15e-303622651e1e&pf_rd_p=751acc83-5c05-42d0-a15e-303622651e1e&pf_rd_r=W6KW0V7YN38ZDAP67ZTY&pd_rd_wg=0kyGD&pd_rd_r=9d279407-9db2-4f77-b1f6-471b54d8cb13&pd_rd_i=B0BW88K9YV&th=1
- Silicone soft tube pipe ID: 4mm, OD: 6mm, lenght: 5 meters Ebay or Amazon: https://www.ebay.com/itm/256028135018?var=555970591215
Or for better chemical resistance: ptfe-lined tubing, viton, PFA/FEP tubes
- 8X M5 screws 40 to 80mm or more depending how much cells you will use. Hardware store, Ebay or Amazon: https://www.amazon.com/Socket-Screws-Stainless-Furniture-Spanner/dp/B0D7P2BT6B/ref=sr_1_4?crid=2WNU7SLHDYFYR&dib=eyJ2IjoiMSJ9.G2CWOdoqw4E157dLAHzvQ9KCwrQjNKaorg3vGuj5LIBllpeTfSxLJbh0YYUF44TXaOaGYDpCbmiW886aTusloPWFsLG4gyfk3V8ssjBXfes-6WWFs6FlW9mrgGgKi3VMkviRDjUkIdwucAmaj9TvoDqgg2Cqo3s3k5dsk6FVmYJTu0qWW0YH1UWSGkzF9jk5O-1n_JPha9ByG7t6DsvgReCtNGqhvT1qnziqTl1kxPg.aM3_F_8ug4IPKaidfJMLre-P2uRetLj4jo7wi09C3Y4&dib_tag=se&keywords=M5%2Bscrews%2B40mm&qid=1745520191&sprefix=m5%2Bscrews%2B40mm%2Caps%2C215&sr=8-4&th=1
- 8X M5 Nuts. Hardware store, Ebay or Amazon
- 4X M2 - M3 screws and nuts (for the pump)
- 4X F four way tube connector (the F four way tube connector is for connecting four cells in case that you will use more as one cell in the battery) Amazon: https://www.amazon.de/-/en/dp/B08BCP941F?ref=ppx_yo2ov_dt_b_fed_asin_title
For the cell:
- Pan based Graphitic carbon felt (for the electrode), thickness: 2 or 3 mm, Ebay or Amazon: https://www.ebay.com/itm/296616788219?_skw=pan+based+graphitic+carbon+felt&itmmeta=01JSMJ1YW2BJBWP99AF7Y1X9RC&hash=item450fbd00fb:g:uJUAAOSw-HJc-bhc&itmprp=enc%3AAQAKAAAA4FkggFvd1GGDu0w3yXCmi1d0TPp66%2BKpqWZD0M%2F1AfLXJEX%2BpGjwWGg7Bbsf1pGyRE7TS9kVXyJyvkcN%2F7mpsDIwDCkyV4qu8h2rkKOvrQD6iHNpqYfMYlCB5gh2PiHwMKmW603xgIMkQIe04jefQ6KkgL%2FHWKcbpReTexEU2%2BfMMeACcwsEBQgp7LWMxjpiSZtAnuxAAfJdva%2FPe4ZBzMSRRYRSNcy%2BEdO1pd9y2TCa5RfDDRmgv%2Fktlr%2Bbkw2nhQTdLmdArF3x9ZsBqC%2FxOyrA3v%2B7LExwHkuFFiIkNgKK%7Ctkp%3ABk9SR4bvh5LNZQ
- Nafion or Fumasep ion exchange membrane (you can use also other separator for some zinc bromine flow battery). The Nafion membrane you can get from the hydrogen fuel cell: https://www.ebay.com/itm/134089603290
- Graphite foil 0.5 to 1mm (for current collector) Ebay or Amazon: https://www.ebay.com/itm/363838508915?_skw=graphite+foil&var=633063293660&itmmeta=01JSMJEN0R4DAE7K2SZAM0VXDZ&hash=item54b6770f73:g:KYYAAOSwlHRfphLX&itmprp=enc%3AAQAKAAAA8FkggFvd1GGDu0w3yXCmi1caoACI7uCKJq9bRUAh65avFHSITsqtBhoNLOrdhiT8h2P%2BIPSLd2IrDSPY8iUvAaA6U%2F6q2fibelZT%2Bzm8Q0FdMmGK3hsYQ%2Fv0w%2F9BgObEN%2FJYGpyUwFp0j7hPxyVO5nG1SSbbFSPfO9%2FgVfVkPTSTOA8DauNDDguYHloSPewp3Zri4LVqGNV17Ws0%2BgvmlOd0JRG6HIr1or%2BoQVyG0CSw3x8%2B2kCK%2BU2In18r65ZX7UitAzQk3OQadP1t1u8DN2oq9SFJdgMJAAWkslDzEMTR8yB6FtJgAiN40hZaAcq2oQ%3D%3D%7Ctkp%3ABFBMyNC6ks1l
- Silicone rubber gasket 0.5mm, Ebay or Amazon: https://www.ebay.com/itm/404571974393?var=674566659409
Or for better chemical resistance you can use viton rubber
I recommend to print the files with the name: tank and pump holder, tank holder and tank holder part 2 with PLA or PETG.
And the files with the name: reactor plate, end plate and reactor plate 2 is better to print with some resin printer (with ABS like resin) because it has better chemical resistance.
The PLA or PETG are not resistant to acid or alkaline based electrolytes and will be dissolved in a short time. But in case that you will use some neutral salt electrolyte in the battery then the cell parts can be printed also with FDM printer.
Do you search for FDM or resin 3D printer? Look into Anycubic printers and use my link and Coupon Code to get $25 OFF. Link: https://store.anycubic.com/?ref=cayrex and the Coupon Code: QDSQJZRPRE
