With reference to ‘fuel cells’ in which hydrogen-rich fuel...
(Correct Answer:- A, 1only)

A fuel cell is a device which produces electric energy, through a chemical reaction. Fuel cells produce electricity in the form of direct current (DC). In a DC circuit, electrons flow in only one direction.

Fuel cells use a positively charged ion (Hydrogen) and an oxidising agent (oxygen).

There are many types of fuel cells, but they all consist of a cathode, an anode, and an electrolyte that allows positively charged (hydrogen) ions to move between the two sides of the fuel cell.

They differ from batteries as they (fuel cells) require the continuous supply of fuel. 

Both batteries and fuel cells produce direct current (D.C).

The working of this fuel cell involved the passing of hydrogen and oxygen into a concentrated solution of sodium hydroxide via carbon electrodes.

The first fuel cell was used by NASA in its satellites and space capsules. 

Fuel cells can be used for power backup in commercial and residential buildings.

Fuel cells can be arranged in stacks like series and parallel connection depending on the requirement of higher voltage (series) and current (parallel).

(National Electric Mobility Mission Plan 2020)

The National Electric Mobility Mission Plan (NEMMP) 2020 was launched by the Government of India in 2013 with the objective of achieving national fuel security by promoting electric and hybrid vehicles. The target is to achieve sales of 6 – 7 million in the hybrid and electric vehicles sector from 2020. 

The government will provide fiscal and monetary incentives for this industry. The expectation is that crude oil worth Rs.62000 crore will be saved due to this.

(FAME and National Electric Mobility Mission Plan)

Under the NEMMP, the government has launched the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles, FAME India Scheme.

This scheme had an initial outlay of Rs. 75 crore.

This scheme is expected to provide a major thrust towards early adoption of electric and hybrid technologies.
