ISRO Tests Fuel Cell in Space for Future Missions

January 6, 2024

The Indian Space Research Organisation (ISRO) successfully tested a fuel cell aboard a PSLV rocket launch on January 1st, 2023. The hydrogen-oxygen fuel cell generated electricity along with heat and water – all essential for human spaceflights.

Ideal for Sustained Space Missions

Such fuel cells are ideal for long duration manned missions as the heat and water byproducts meet thermal and consumption requirements. ISRO aims to deploy these zero-emission cells for upcoming space stations.

Key Technical Details

The demonstration fuel cell designed by ISRO’s Vikram Sarabhai Space Centre provided 180W power during its short orbital test. It is a precursor to more advanced systems needed for India’s planned space station by 2035.

Additional Experiments Onboard

The fuel cell was one of 10 experiments by ISRO and startups aboard the PSLV’s Orbital Experimental Module. Others focused on radiation shielding, amateur radio tests, and satellite propulsion systems.

Future Launch Applications

Besides having space applications, such fuel cells can replace vehicle engines on Earth given their high efficiency and zero emissions. During the tests, ISRO also checked lower cost Lithium-ion batteries with advanced graphite-silicon anodes offering mass savings.

Test Platform

Instead of burning up in the atmosphere, ISRO now uses spent upper rocket stages of its PSLVs as an orbital platform for testing new technologies in space conditions before deployment in satellites.

The successful demonstration of a fuel cell sustaining in space is a stepping stone for ISRO in developing and maturing eco-friendly energy systems for ambitious future programs like manned missions.
