Hydrogen fuel cell demonstrator with electric motor, ammeter, and voltmeter Key benefits Ready demonstration of hydrogen fuel cell to mechanical work conversion: the fuel cell provides electrical output that can be measured and used to run the included electric motor with wind shoulder. Builtin measurement: ammeter and voltmeter are integrated so users can monitor current and voltage in real time for testing, instruction, and data collection. Optimized electrode size for improved conversion: the two proton exchange membrane electrodes in the base and demonstrator are 35mm x 35mm to help improve conversion rates during experiments. Clear system boundaries: does not contain hydrogen generators, so hydrogen must be supplied separately. This separation simplifies setup choices and allows use with a hydrogen source appropriate to the application. Main functions and attributes Function: Converts hydrogen fuel cell output into electrical power, provides measurement of electrical parameters, and drives an electric motor for visible mechanical output. Electrical part: Electric motor with wind shoulder, plus an ammeter and a voltmeter for monitoring performance. Hydrogen fuel cell: Proton exchange membrane type with two electrodes; electrode dimensions in both the base and the demonstrator are 35mm x 35mm. Compatibility: Designed for educational, laboratory, and prototype demonstration setups where an external hydrogen source is available. Performance: Electrode sizing is chosen to improve conversion efficiency under typical demonstration loads. Actual performance depends on hydrogen supply, load conditions, and operating environment. Practical details Electrode size: 35mm x 35mm for both PEM electrodes in the base and the demonstrator to enhance conversion behavior. Supply note: Hydrogen generation equipment is not included. Users must provide hydrogen supply and follow appropriate handling procedures for that supply. Measurement capability: Integrated ammeter and voltmeter enable straightforward measurement of voltage and current without additional instruments. Mechanical output: The electric motor with wind shoulder converts the fuel cell electrical output into rotational motion for visible demonstrations or small load testing. Typical use scenarios Classroom demonstration: Show the relationship between hydrogen fuel cell voltage and current while driving the motor to demonstrate energy conversion in a controlled learning environment. Laboratory prototyping and testing: Use the demonstrator to evaluate fuel cell behavior, collect voltage and current data, and test small mechanical loads or motordriven components. Trade show or exhibition demo: Provide a visible, measurable display of fuel cell output driving an electric motor while attendees observe readings on the voltmeter and ammeter. What is included and what to plan for Included: Electric motor with wind shoulder, ammeter, voltmeter, and the hydrogen fuel cell with two 35mm x 35mm proton exchange membrane electrodes in the base and demonstrator. Not included: Hydrogen generation or hydrogen supply equipment. Users must arrange a compatible hydrogen source and any required supply hardware separately. This product is intended for educational, experimental, and demonstration use where a separate hydrogen source is available.
