Established as
College of Engineering in 1961, the Institute was later declared as an
Institution of National Importance under the “Institutes of Technology
(Amendment) Act, 1963” and was renamed as “Indian Institute of Technology
Delhi”. It was then accorded the status of a Deemed University with powers to
decide its own academic policy, to conduct its own examinations, and to award
its own degrees.
Ecosense recently installed “AEM based Hydrogen Generation System” at Department of Electrical Engineering, Indian Institute of Technology, Delhi.
AEM based hydrogen generation system
is a technology that utilizes an AEM (Alkaline Electrolyte Membrane) to
generate hydrogen gas through an electrochemical process known as water
electrolysis. This system uses an AEM as electrolyte instead of a traditional
solid polymer electrolyte, allowing for more efficient and cost-effective
hydrogen production. The hydrogen produced can be used for various purposes,
such as energy storage, fuel for transportation and as feedstock for chemical
industry.
AEM based hydrogen generation system
work by splitting water into hydrogen and oxygen through electrolysis. During
this process, an electrical current is passed through an aqueous solution
containing a positive and negative electrode. The positive electrode, called
anode, oxidizes water to release oxygen gas. The negative electrode, called
cathode, reduces water to generate hydrogen gas. The AEM acts as the
electrolyte and serves to separate the two electrodes and transport ions
between them.
Advantages of using an AEM in hydrogen
generation over traditional solid polymer electrolytes include:
· Higher ionic
conductivity, which leads to improved efficiency and lower energy consumption.
· More tolerant to
containments and impurities, leading to improved durability and longer
lifespan.
· Higher operating
temperatures, allowing for more compact and cost-effective designs
The system uses an AEM based hydrogen
generation setup along with a water purification/deionisation system and a
hydrogen dryer. When the Hydrogen Generation setup is powered via a Renewable
source, the hydrogen produced is known as “Green Hydrogen”.
Generation Process:
Step1: De-ionisation of water using
distillation setup
Step2: Hydrogen Generation from AEM
Electrolyser
Step3: Hydrogen Drying through a
desiccant based hydrogen dryer
Step4: Collection of 99.9% pure
hydrogen into a pressurized tank.

Ecosense also conducted a master’s
training. This master’s training program was designed to educate and prepare
professors, researchers and technicians in Green Technologies who would go on
to instruct thousands of students and professionals in this sector as they
launch their careers or businesses.
Program Outcomes
The instructors and students had a
great time working on the lab equipment and will use this setup to further
their research in this very field.
