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.

I've 10 months to decide whether I want to play one more year: Dhoni on IPL future
New Delhi(PTI): The legendary MS Dhoni stayed immune to the growing clamour around his future in the IPL, saying the decision to bring curtains on his career depends on how his body reacts to the demands of top-flight cricket and he has "10 months" to take a call.
In this IPL, Dhoni has not been able to make the kind of impact that he usually does while batting in the lower middle-order.
His lack of timing and ineffectiveness, evidenced in the 76 runs that he made from four matches, have prompted several experts to urge the multiple World Cup-winning skipper to move on.
"I am still playing the IPL and it is one year at a time for me. I am 43 now and by the end of this IPL season, I will be 44," Dhoni said on entrepreneur Raj Shamani's podcast recently.
"So, I have 10 months to decide whether I want to play one more year and it's not me to decide as it is my body that decides whether I can play or not," he added.
However, the former Chennai Super Kings skipper, who led CSK to five IPL titles, said he is quite content with his achievements on the field.
"It is not about whether I am happy or unhappy. Whatever has happened has happened. It cannot be changed. It's about accepting all of it. You know, whatever happens I will not be able to add one more run to my international runs, and no one will be able to reduce them," he said.
Dhoni has always been a man of the present. But, for once, he set aside that pragmatic side to reveal his wish of seeing legends like Sachin Tendulkar, Sourav Ganguly, Virender Sehwag and Yuvraj Singh assemble in the same team once again.
"I will stick to Indian players. Viru pa opening the innings, Sachin, Dada… and now you imagine everyone at their prime. Then you will get this feeling that there can't be anyone better than them.
"It's tough to pick an all-time eleven. Now, when you see Yuvi hitting six sixes, you will feel that I don't want to watch any other batsman. It's all about enjoying what they have done for India. Some of those talents we have seen are mind blowing," he added.
