Fuel Cell Lab

With the sudden rise in interest of Electric Vehicle technology, Fuel Cells are making their way back into energy ecosystem. Ecosense’s Fuel Cell lab is focused on familiarizing user with Hydrogen Fuel Cell technology and enabling them to design a micro–Fuel Cell enabled standalone system.

Ecosense’s Fuel Cell Training system is a standalone Fuel Cell system, the output of fuel cell is connected to a charge controller and charge controller is further connected to a battery, an inverter, and AC and DC Loads to run utilities.

Fuel Cell unit receives dry hydrogen from the Hydrogen gas cylinder at preset LPM. The generated power can be used directly by a DC load but as per the V-I curve of Fuel cell system, the voltage reduces as we increase the load, therefore, the power generated by fuel cell system cannot be used directly hence the output is connected to a charge controller which charges the battery and maintain output as per the battery voltage. The battery bank is further connected to a home inverter so that home utilities can be used as a load for the fuel cell system.

By using the Fuel Cell training system, a user will be able to understand characteristics of fuel cell with the help of resistive load or DC-DC converter, output power variation of fuel cell with change in hydrogen supply, fuel cell performance with DC/AC load and output variation of fuel cell with a change in temperature.
