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.

Sabarimala gold loss: How did the accused reach Rahul's home, asks Vijayan
Thiruvananthapuram (PTI): Kerala Chief Minister Pinarayi Vijayan on Tuesday hit back at Rahul Gandhi for targeting the ruling CPI(M) over the Sabarimala gold loss case during a poll campaign, questioning how the accused in the case had managed to reach the Congress leader's home.
The Marxist veteran was apparently referring to a widely circulated purported photograph in which the prime accused in the Sabarimala gold loss cases, Unnikrishnan Potty, accompanied by some senior Congress leaders, was seen with Sonia Gandhi at her residence in Delhi.
He also said people have already given a reply to Rahul, the Leader of Opposition in the Lok Sabha, on this matter.
The CM's reaction came a day after Rahul sang a line from a popular parody song about CPI(M) leaders' alleged roles in the gold theft at the Sabarimala temple while addressing a corner meeting as part of the assembly polls campaign in Pathanamthitta district.
As he sang the line "swarnam kattathu aarappa" (who stole the gold of Ayyappa) from a song used by the Congress-led UDF to target the ruling Left during the local body polls a few months ago, at the meeting in Pathanamthitta -- the district where the hill shrine of Lord Ayyappa is located-- the crowd cheered Rahul.
Soon after Gandhi targeted the Left party over the gold loss issue, CPI (M) activists began a social media campaign making allegations against his mother and former party chief Sonia Gandhi in connection with the matter.
While replying to a question regarding this, CM Vijayan said the Congress leader already got a befitting reply and should he also repeat the same.
"If he thinks about how all those who were involved in the stealing had reached his home...then he will get a reply. Anyway, we don't have any such flaws," Vijayan added.
Attacking the Left and the BJP over the Sabarimala gold loss issue, Rahul Gandhi on Monday had said that Prime Minister Narendra Modi had forgotten about what happened in Sabarimala, during his visit to Palakkad as part of election campaign.
Rahul claimed that the prime minister remained silent to avoid damaging the LDF.
He had also said that a UDF government would ensure that those responsible for alleged irregularities related to the temple are punished.
