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.

Karnataka Assembly passes bill on Palace Grounds amid opposition protest
Bengaluru, Mar 6 (PTI): The Karnataka Assembly on Thursday passed the Bangalore Palace (Utilisation and Regulation of Land) Bill, reaffirming state ownership over 472 acres and 16 guntas of land here, amid protests by the opposition BJP.
During the discussion, Karnataka Law and Parliamentary Affairs Minister H K Patil said the state government would have to provide Rs 200 crore worth of Transfer of Development Rights (TDR) for each acre of land, which means that for 15 acres, Rs 3,000 crore worth of TDR would be issued.
“If we accept it, then this 2-km stretch of road will become the costliest road in the world. If we accept it then how are we going to develop the city in later stages? How will you carry out development works?” asked Patil.
He also pointed out that this question was raised not only under the Congress government but also during the previous BJP regime.
However, the BJP-led cabinet has opposed the project.

“Suppose we agree to it then, what will be the valuation of the 472 acres? It will be lakhs and lakhs of crores of rupees. Can we accept?” Patil wondered.
The Minister said the government had previously exercised its executive powers to issue an ordinance, which was approved by the Governor. Now the government is bringing a bill with two amendments.
“In this bill, we have made provisions either to develop or drop the road development work,” Patil explained.
However, BJP state president B Y Vijayendra and BJP MLA Arvind Bellad opposed the move, alleging that the government was targetting Yaduveer Krishna Datta Chamaraja Wadiyar, the scion of the Mysuru royal family, and the BJP MP from Mysuru-Kodagu constituency out of political vendetta.
“We talk of 472 acres of Mysuru Maharaja but here there are many Maharajas who too own 400 acres, 500 acres and thousands of acres of land, which is known to everyone,” Bellad said.
He slammed the Congress government, saying political power should not be misused for personal vendetta.
“Why (the then Deputy Chief Minister) Siddaramaiah brought the law in 1996 pertaining to the Bangalore Palace? Why are you setting eyes on the Bangalore Palace?” he asked.
Vijayendra charged that Wadiyar won the election on BJP ticket so the state government realised that it should acquire it.
“This bill has been brought for political vengeance. We are not discussing whether Rs 3,000 crore is exorbitant or not but the moment Yaduveer became MP, the state government woke up. You should be ashamed. This house should not be used for political vendetta,” he said.
Intervening, Minister Priyank Kharge said Vijayendra should not have raised it because the intention behind building the road was noble.
According to him, the BJP too had the same plan when it was in power.
He sought to know whether thousands of crores of rupees be spent on a road which should have cost significantly less.
In response, BJP MLA B A Basavaraj (Byrathi) said issuing TDR will not be a burden on the state government and appealed to the ruling Congress to reconsider its stance.
Minister Ramalinga Reddy too explained that the Karnataka government acquired the entire land way back in 1996.
The Mysuru royal family went to the High Court, which gave ruling in favour of the state government. The royal family then approached the Supreme Court, where the case is still going on, the Minister pointed out.
“The final judgment is pending in the SC to decide whether the acquisition was right or wrong. If the SC says it’s the royal family’s property then let it be so. If the order is in the state government’s favour then we can take a decision. The bill is only about it,” Reddy explained.
Speaker U T Khader then called for a voice vote and the bill was passed by the Assembly amidst opposition BJP’s discontent.
