ISRO successfully flight-tests fuel cell to assess its operation in space
Bengaluru, Jan 5: ISRO on Friday said that it has successfully flight-tested a fuel cell to assess its operation in space and to collect data to facilitate the design of systems for future missions.
Powering missions with efficiency and emitting only water, these fuel cells are the future for power production in space habitats, the national space agency headquartered here said.
Vikram Sarabhai Space Centre/ISRO successfully tested a 100 W class Polymer Electrolyte Membrane Fuel Cell based Power System (FCPS) in its orbital platform POEM3, launched onboard PSLV-C58 on January 1.
"The objective of the experiment was to assess Polymer Electrolyte Membrane Fuel cell operation in space and to collect data to facilitate the design of systems for future missions," ISRO said in a statement.
During the short duration test onboard POEM, 180 W power was generated from Hydrogen and Oxygen gases stored onboard in high pressure vessels.
"It provided a wealth of data on the performance of various static and dynamic systems that formed part of the power system and the physics at play," the space agency said.
Hydrogen fuel cells produce electricity directly from Hydrogen and Oxygen gases, along with pure water and heat. It is an electric generator which works on electrochemical principles, as in batteries, as against the combustion reactions employed in conventional generators, it was noted.
The ability to produce electricity directly from fuels without any intermediate step renders it very efficient. With water as the only byproduct, they are totally emission-free. These features make them ideal candidates for space missions involving humans where electric power, water and heat are essential, since a single system can meet multiple requirements in the mission, according to ISRO.
Fuel cells also possess significant societal application potential. They are also considered to be the most appropriate solution to replace the engines of various types of vehicles in use today and to power standby power systems.
They can provide a range and fuel recharge time equaling that of today's conventional engine, which gives them a distinct advantage over batteries, and are expected to facilitate emission-free transportation.
Fuel cell is an ideal power source for the space station as it provides both power and pure water, ISRO added.

In phone call, PM Modi, US President Trump resolve to promote global peace, security
New Delhi, Jan 27 (PTI): Prime Minister Narendra Modi and US President Donald Trump on Monday vowed to work towards a "trusted" partnership between India and US and advance global peace and security in their first phone conversation since the American leader's inauguration last week.
Modi and Trump exchanged views on global issues, including the situation in West Asia and Ukraine, and deliberated on measures to boost bilateral cooperation in areas such as technology, trade, investment, energy and defence, an Indian readout said.
The two leaders agreed to meet soon, it said.
"Delighted to speak with my dear friend President @realDonaldTrump @POTUS.
Congratulated him on his historic second term," Modi said on 'X'.
"We are committed to a mutually beneficial and trusted partnership. We will work together for the welfare of our people and towards global peace, prosperity, and security," he said.
In a statement, the Prime Minister's Office (PMO) said the two leaders "reaffirmed" their commitment for a "mutually beneficial and trusted partnership".
"They discussed various facets of the wide-ranging bilateral Comprehensive Global Strategic Partnership and measures to advance it, including in the areas of technology, trade, investment, energy and defence," it said.
"The two leaders exchanged views on global issues, including the situation in West Asia and Ukraine, and reiterated their commitment to work together for promoting global peace, prosperity and security," the PMO said.
"The leaders agreed to remain in touch and meet soon at an early mutually convenient date," it added.
It is not immediately known whether the issues of immigration and tariff figured in the talks.
Like in many countries, there have been some concerns in India as well over the Trump administration's approach on immigration and tariff.
President Trump has already talked about slapping "100 per cent tariffs" on the BRICS grouping, a bloc that includes India too.
It is learnt that the phone call was initiated from the Indian side.
External Affairs Ministry Spokesperson Randhir Jaiswal said last week that India is looking for "bolder, bigger and a more ambitious" relationship with the US and indicated its readiness to work with the Trump administration to address issues like illegal immigration and trade.
The phone conversation between Modi and Trump came six days after External Affairs Minister S Jaishankar held separate meetings with US Secretary of State Marco Rubio and National Security Advisor Mike Waltz in Washington.
Jaishankar also attended the Quad foreign ministers' meeting in the American capital. The meeting was the Trump administration's first foreign policy engagement.
At a media briefing in Washington on January 22, Jaishankar said his meetings signalled that the Trump administration "prioritising" the bilateral relationship with India.
The external affairs minister also said that there was agreement between the two sides about the need to be bolder, bigger, and more ambitious about the bilateral relationship.
Asked about the Trump administration's policy on tariff and immigration, Jaiswal said on Friday that India is looking at addressing issues in a constructive manner.
"Our approach has always been to address issues in a constructive manner which is in keeping with the interests of both countries," he had said at his weekly media briefing last week.
"We remain in close communication with the US administration and would like to continue to work towards strengthening our economic partnership further," he said.
India is also keen to continue cooperation under the Initiative on Critical and Emerging Technology (iCET) that was launched during the tenure of the Biden administration.
