{"product_id":"fuel-cell-stack","title":"Fuel Cell Stack","description":"\u003cp\u003eH-TEC's Fuel Cell Stacks are modular fuel cell stacks with cells that are easy to add or remove. The Fuel Cell Stack 5 allows voltages between individual cells to be measured. The stack is delivered fully assembled.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eAbout the PEM Fuel Cell Process\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cp\u003eHydrogen gas is oxidized within a fuel cell. In the process, the chemical energy stored in the hydrogen gas is converted directly, i.e., without combustion, to electrical energy. This process takes place in the heart of the fuel cell, the Membrane Electrode Assembly (MEA).\u003c\/p\u003e\n\n\u003cp\u003eThe MEA comprises two electrodes (cathode: oxygen side and anode: hydrogen side) and the Proton Exchange Membrane (PEM). The PEM is a special plastic film which is permeable to protons but which presents a barrier to electrons.\u003c\/p\u003e\n\n\u003cp\u003eHydrogen gas is split by catalysis into electrons and protons in the fuel cell. 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 Specification\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: 3cm² 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: 3cm² 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: 3cm² 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 — f110 fuel cell stack 10 fc stack potential vs current updated\" 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 — f110 fuel cell stack 10 fc stack power vs current updated\" 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\/F109_FuelCellStack5_02.png?v=1789066693","url":"https:\/\/h-tec-education.com\/products\/fuel-cell-stack","provider":"H-TEC Education","version":"1.0","type":"link"}
