ISRO: The Indian Space Research Organisation (ISRO) has reported the successful testing of a 100 W class Polymer Electrolyte Membrane Fuel Cell based Power System (FCPS) on its orbital platform, PSLV Orbital Experimental Module-3 (POEM3). The experiment, which was launched aboard the Polar Satellite Launch Vehicle (PSLV-C58) on January 1, was a critical step in examining the operation of Polymer Electrolyte Membrane Fuel cells in space.
Objective of the Experiment
The major goal of this experiment, according to ISRO, was to collect useful data that will aid in the design of systems for future space missions. Using Hydrogen and Oxygen gases stored in high-pressure tanks, the Polymer Electrolyte Membrane Fuel Cell generated 180 W of power during the short-duration test onboard POEM3.
Data Generation and Analysis
The test generated a plethora of data on the functioning of several static and dynamic systems important to the power system, revealing light on the physics at work in space. Polymer Electrolyte Membrane Fuel Cells directly generate electricity while also producing pure water and heat.
Divergence from Traditional Generators
Unlike traditional generators that use combustion processes, these fuel cells use electrochemical principles akin to batteries. Their remarkable efficiency originates from their capacity to generate power directly from fuels. Furthermore, they produce no emissions and merely produce water as a byproduct. These fuel cells are a suitable alternative for human-manned space missions since they can meet the key requirements of electric power, water, and heat in a single system. Fuel Cells’ emission-free and efficient nature puts them as critical components for future space homes.
