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.

Temple stampede: North Goa collector, SP shunted out
Panaji (PTI): Hours after six devotees lost their lives in a stampede during a temple festival in Goa, the state government on Saturday ordered the transfer of five senior officials, including the North Goa collector and the superintendent of police.
"In order to ensure free and fair inquiry, the government has transferred District Collector Sneha Gitte, Superintendent of Police (North) Akshat Kaushal, Deputy Superintendent of Police (Bicholim) Jivba Dalvi, Deputy Collector (Bicholim) Bhimnath Khorjuvekar and Police Inspector Dinesh Gadekar with immediate effect," Chief Minister Pramod Sawant told reporters.
Addressing a press conference in Panaji, Sawant said a fact-finding committee, headed by State Revenue Secretary Sandeep Jacques and comprising senior police officer Varma Sharma, Parimal Abhishekh, State Director of Transport, and Tikam Singh Varma, SP, South Goa, as its members has been constituted.
Sawant said the panel will visit the stampede site at Shirgao village and prepare a report after speaking with all the concerned persons, including the Superintendent of Police, Collector, and officials of Fire and Emergency Services.
The committee will submit its report by Sunday morning.
Sawant said the death toll remains six. Eleven injured people were admitted to Goa Medical College and Hospital and five of them are on the ventilator, while eight persons are undergoing treatment in North Goa District Hospital.
