Due to the chemical imbalance created, the protons (cations) diffuse through the PEM. The resulting potential difference can be tapped on the electrodes in the form of a no-load voltage. As soon as an electric circuit is connected to the fuel cell, the surplus electrons flow to the cathode, where they combine with the oxygen and the protons to form water (H\u003csub\u003e2\u003c\/sub\u003eO). The water produced escapes via the air vent in the form of water vapor.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Hydrogen Supply:\u003c\/strong\u003e  Electrolyzer 65\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eFuel Cell Stack Features:\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eModular design\u003c\/li\u003e\n\u003cli\u003eFlexible power output\u003c\/li\u003e\n\u003cli\u003eSingle gas supply for whole stack\u003c\/li\u003e\n\u003cli\u003eEasy to add or remove cells from the fuel cell stack\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eStack 3:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\nPower Per Cell: 200 mW\u003c\/li\u003e\n\u003cli\u003eTotal Power (3 Cells): 600 mW\u003c\/li\u003e\n\u003cli\u003eGenerated Voltage: 0.4 - 0.96 V per cell\u003c\/li\u003e\n\u003cli\u003eElectrode Area: 3 cm² per cell\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D): 2.4\" x 3.7\" x 2.8\" (60 x 95 x 70 mm)\u003c\/li\u003e\n\u003cli\u003eWeight: 7.4 oz (211 g)\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eStack 5:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\nPower Per Cell: 200 mW\u003c\/li\u003e\n\u003cli\u003eTotal Power (5 Cells): 1 W\u003c\/li\u003e\n\u003cli\u003eGenerated Voltage: 0.4 - 0.96 V per cell\u003c\/li\u003e\n\u003cli\u003eElectrode Area: 3 cm² per cell\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D): 2.4\" x 4.7\" x 2.8\" (60 x 120 x 70 mm)\u003c\/li\u003e\n\u003cli\u003eWeight: 10.2 oz (288 g)\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eStack 10:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\nPower Per Cell: 200 mW\u003c\/li\u003e\n\u003cli\u003eTotal Power (10 Cells): 2 W\u003c\/li\u003e\n\u003cli\u003eGenerated Voltage: 0.4 - 0.96 V per cell\u003c\/li\u003e\n\u003cli\u003eElectrode Area: 3 cm² per cell\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D): 2.4\" x 7\" x 2.8\" (60 x 178 x 70 mm)\u003c\/li\u003e\n\u003cli\u003eWeight: 15.2 oz (430 g)\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n\u003cimg alt=\"Fuel Cell Stack 10 polarization curve: stack voltage vs current\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0825\/9544\/7007\/files\/f110-fuel-cell-stack-10-fc-stack-potential-vs-current-updated.jpg?v=1788466858\"\u003e\u003cimg alt=\"Fuel Cell Stack 10 power curve: stack power vs current\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0825\/9544\/7007\/files\/f110-fuel-cell-stack-10-fc-stack-power-vs-current-updated.jpg?v=1788466888\"\u003e\n\u003c\/p\u003e","brand":"H-TEC Education","offers":[{"title":"3","offer_id":51303887896799,"sku":"12120033","price":220.0,"currency_code":"USD","in_stock":true},{"title":"5","offer_id":51303887929567,"sku":"12120034","price":308.0,"currency_code":"USD","in_stock":true},{"title":"10","offer_id":51303887962335,"sku":"12120035","price":578.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0825\/9544\/7007\/files\/FCStack_Small_9ef9d98b-f71f-4843-ab0d-520c1da72a58.png?v=1791909980"},{"product_id":"fuel-cell-science-fair-kit-j105","title":"Fuel Cell Science Fair Kit","description":"\u003cp\u003eThis kit has everything needed to perform simple science experiments using fuel cell technology.
