ISRO Successfully Tests Polymer Electrolyte Membrane Fuel Cell on PSLV-C58.

Science & Technology | Dated: 02 jan 2026

The Indian Space Research Organisation (ISRO) successfully tested a 100 W class Polymer Electrolyte Membrane Fuel Cell (PEMFC) based Power System in its orbital platform, POEM-3. This experiment was part of the PSLV-C58 mission. Fuel cells are ideal for space stations as they produce both electricity and pure water from hydrogen and oxygen.

🎯 Key Highlights:

  • The fuel cell generated 180W power during the test.
  • It is a precursor to power systems for the proposed Bhartiya Antariksh Station.
  • The byproduct, water, is crucial for sustaining astronauts in space.

💡 Other Important Facts:

  • Tech: Polymer Electrolyte Membrane Fuel Cell.
  • Platform: POEM-3 (PSLV-C58).
  • Utility: Space Station Power & Water.
