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.

US President Donald Trump announces 27 percent reciprocal tariff on India
Washington/New Delhi (PTI): The US has announced 27 percent reciprocal tariffs on India saying New Delhi imposes high import duties on American goods, as the Donald Trump administration aims to reduce the country's trade deficit and boost manufacturing.
The move is expected to impact India's exports to the US. However, experts say that India is better-placed than its competitors who also face increased levies.
President Trump, in a historic measure to counter higher duties on American products imposed globally, announced reciprocal tariffs on about 60 countries.
"This is Liberation Day, a long-awaited moment. April 2, 2025 will forever be remembered as the day American industry was reborn, the day America's destiny was reclaimed, and the day that we began to make America wealthy again. We are going to make it wealthy, good, and wealthy," Trump said in his remarks from the Rose Garden at the White House on Wednesday.
He said that the United States charges other countries only a 2.4 percent tariff on motorcycles, but Thailand and others are charging much higher rates, like 60 percent, India 70 percent, Vietnam 75 percent, and others charge even higher rates.
As he announced the tariffs, he held up a chart that showed the tariffs that countries such as India, China, the UK, and the European Union charge, along with the reciprocal tariffs that these countries will now have to pay.
The chart indicated that India charged 52 percent tariffs, including currency manipulation and trade barriers, and America would now charge India a discounted reciprocal tariff of 26 percent. But according to the White House documents, there will be a 27 percent duty on India.
"India, very, very tough. Very, very tough. The prime minister just left. He's a great friend of mine, but I said, you're a friend of mine, but you're not treating us right. They charge us 52 percent. You have to understand, we charge them almost nothing for years and years and decades, and it was only seven years ago, when I came in, that we started with China," Trump said.
Describing the tariffs as a "mixed bag and not a set back", an official in India said the commerce ministry is analysing the impact of 27 percent reciprocal tariffs imposed by the US on India.
According to the official, the universal 10 percent tariffs will come into effect on all imports into the US from April 5 and from April 10, 27 per cent duty will come into play.
"The ministry is analysing the impact of the announced tariffs," the official said, adding there is a provision that if a country would address the concerns of the US, the Trump administration can consider reducing the duties against that nation.
India is already negotiating a bilateral trade agreement with the US. The two countries are aiming to finalise the first phase of the pact by fall (September-October) of this year.
"It is a mixed bag and not a setback for India," the official said.
Exporters' body FIEO stated that the duties on India will undoubtedly affect domestic players but early conclusion of the trade agreement would provide relief from these tariffs.
"We have to assess the impact, but looking at the reciprocal tariffs imposed on other countries, we are in a lower band. We are much better placed compared to our key competitors such as Vietnam, China, Indonesia, Myanmar, etc. We will definitely be affected by the tariffs, but we are much better placed than many others," Federation of Indian Export Organisations (FIEO) Director General Ajay Sahai told PTI.
From 2021-22 to 2023-24, the US was India's largest trading partner. The US accounts for about 18 per cent of India's total goods exports, 6.22 per cent in imports, and 10.73 per cent in bilateral trade.
With America, India had a trade surplus (the difference between imports and exports) of USD 35.32 billion in goods in 2023-24. This was USD 27.7 billion in 2022-23, USD 32.85 billion in 2021-22, USD 22.73 billion in 2020-21, and USD 17.26 billion in 2019-20.
In 2024, India's main exports to the US included drug formulations and biologicals (USD 8.1 billion), telecom instruments (USD 6.5 billion), precious and semi-precious stones (USD 5.3 billion), petroleum products (USD 4.1 billion), gold and other precious metal jewellery (USD 3.2 billion), ready-made garments of cotton, including accessories (USD 2.8 billion), and products of iron and steel (USD 2.7 billion).
Imports included crude oil (USD 4.5 billion), petroleum products (USD 3.6 billion), coal, coke (USD 3.4 billion), cut and polished diamonds (USD 2.6 billion), electric machinery (USD 1.4 billion), aircraft, spacecraft and parts (USD 1.3 billion), and gold (USD 1.3 billion).
