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.

England sticking with Key, McCullum and Stokes despite Ashes humbling
London (AP): England is not sacking anybody following the 4-1 Ashes loss in Australia.
A review of the tour by the England and Wales Cricket Board, announced within hours of the final match in January, was concluded on Monday. Firing people would “be the easy thing to do,” ECB chief executive Richard Gould said but he insisted, "This is not the time to throw everything out."
Managing director Rob Key, coach Brendon McCullum and captain Ben Stokes kept their jobs after the best England side to go to Australia in 14 years lost the Ashes in 11 days with two games to spare.
“Moving people on can sometimes be the easy thing to do. That's not the route that we're going to take,” Gould said. “I've seen the driving ambition and determination that we're lucky enough to have within our leadership group to take the lessons from the Ashes and move forward.”
Gould previously was the chief executive of Bristol City soccer club and said the ECB would not follow the same route as soccer's hire-and-fire culture.
“Cricket is a very unique sport in that it takes a team of leadership ... it's not like football where there's a single point of failure or success with a manager," he said. He added the ECB would not “select or deselect management based on a popularity campaign.”
The main criticisms of England's tour were poor preparation, player misbehavior, and selection mistakes.
At a press conference at Lord's, Gould and Key said McCullum and Stokes have not had a “bust up,” they did not want McCullum to “completely change” but “to evolve,” the behavior of some players was “unprofessional,” there will be more consequences for underperforming, and a commitment to “better long-term planning” ahead of major test series.
Some changes were already implemented for the Twenty20 World Cup, where England reached the semifinals. Gould implied that performance saved McCullum.
Key acknowledged that England supporters would be disappointed to see the management team go unpunished.
“I know people want punishment and that people then should be sacked for that,” Key said. “That doesn't mean we don't feel like we've gone through some serious pain: Brendon, myself, Ben. It's been as tough a time as I think I've had.”
