{"product_id":"cfershtec","title":"Sealed H-Type Electrochemical Cell (50mL+50mL) for Fundamental Electrochemistry Research, CFERSHTEC","description":"\u003cp\u003eAn H-type electrochemical cell (or H-cell) is the most ubiquitous reactor in electrochemistry research for applications that require the physical and chemical separation of the anode and cathode chambers. It is named for its distinctive \"H\" shape, where two vertical glass compartments are connected by a horizontal bridge. This bridge typically contains a membrane or a glass frit that allows ions to move between chambers to complete the circuit while preventing the gaseous or liquid products formed at one electrode from reaching and interfering with the other.\u003c\/p\u003e\n\u003cp\u003eThe H-cell is specifically chosen over a single-chamber cell for several reasons: (1) \u003cstrong\u003eProduct Separation\u003c\/strong\u003e: In CO2 reduction (CO2RR), the oxygen produced at the anode can diffuse to the cathode and be re-reduced, which ruins Faradaic efficiency. The H-cell prevents this \"back-reaction\". (2) \u003cstrong\u003epH Asymmetry\u003c\/strong\u003e: The different pH levels in each chamber can be well maintained (e.g., an acidic anode for oxygen evolution and a neutral cathode for CO2 reduction). (3) \u003cstrong\u003eCross-Contamination Prevention\u003c\/strong\u003e: It prevents dissolved metal ions (like Platinum from a counter electrode) from migrating and plating onto the working electrode.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eCFERSHTEC (C-FER-SHTEC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eThe whole electrochemical cell body is made of glass material with high B content\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe H-type electrochemical cell is composed of two 50 mL individual chambers.\u003c\/li\u003e\n\u003cli\u003eThe O-ring was used for cell chamber sealing.\u003c\/li\u003e\n\u003cli\u003eA membrane or glass frit can be placed between the cells as the clamp was used to fix\/tight them.\u003c\/li\u003e\n\u003cli\u003eThe sample is hold by an electrode holder with I.D. of 6 mm and immersed in the electrolyte.
