{"product_id":"ersofects","title":"Reversible SOFC\/SOEC Testing System with PLC and HMI Units, ERSOFECTS","description":"\u003cp\u003eAn integrative testing system for Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolysis Cells (SOEC) is a sophisticated laboratory or industrial rig designed to evaluate electrochemical performance, durability, and thermal cycling. Since these systems operate at high temperatures (600 °C to 900 °C), they require precise coordination between gas handling, thermal management, and electrical characterization.\u003c\/p\u003e\n\u003cp\u003eAn integrative test stand is generally composed of four primary modules: \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermal Management Module\u003c\/strong\u003e: (1) \u003cem\u003eHigh-Temperature Furnace\u003c\/em\u003e: Typically a split-tube or box furnace with multi-zone heating to ensure a uniform temperature profile across the cell or stack. (2) \u003cem\u003ePre-heaters\u003c\/em\u003e: Used to heat incoming gases to the operating temperature before they reach the ceramic interface, preventing thermal shock. (3) \u003cem\u003eHeat Exchangers\u003c\/em\u003e: In larger \"stack\" testing, these recover heat from exhaust gases to improve system efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGas Processing \u0026amp; Delivery (Balance of Plant)\u003c\/strong\u003e: (1)\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003eMass Flow Controllers (MFCs)\u003c\/em\u003e: High-precision units to manage fuel (H2, CH4, CO, NH3) and oxidants (Air, O2). (2) \u003cem\u003eHumidification \u0026amp; Steam Generation\u003c\/em\u003e: Critical for SOEC mode (electrolysis) and preventing carbon coking in SOFC mode.
