Romtek Basic Hydrogen Fuel Cell Apparatus

 

 

 

        Romtek Basic Hydrogen Fuel Cell Apparatus demonstrates & enables detailed experiments on harnessing renewable energy to power the cars of the future. It incorporates multidisciplinary technologies and is useful to educators & experimenters in Physics & Chemistry; Electronics & Mechanical Engg. & Non-Conventional Energy Sciences.

 How it Works

         The apparatus uses a PEM (Polymer Electrolyte Membrane) reversible, bi-modal fuel cell, a solar panel, a dc motor driven, scaled down automobile, a winch attachment for lifting a small mass & electronics control module.

                      In mode One, fuel Cell works as Electrolyser, accepting electricity obtained from sunlight, to electrolyse distilled water to Hydrogen & Oxygen, which is then stored in a graduated container. In mode 2, the Fuel Cell accepts the stored Hydrogen & Oxygen as input and generates electricity. The generated electricity drives a dc motor, which drives the model 4-wheeled vehicle. Provision is there for the motor to lift a known small mass using a winch attachment to directly measure mechanical work done. A block diagram illustrates the processes:
