Which one of the following is the exhaust pipe emission from Fuel Cell Electric Vehicles, powered by hydrogen ?

  1. Hydrogen peroxide
  2. Hydronium
  3. Oxygen
  4. Water vapour
Show answer and solution

Correct answer: D. Water vapour

Answer: D. The exhaust emission from a hydrogen Fuel Cell Electric Vehicle is WATER VAPOUR. In a hydrogen FCEV, hydrogen (H2) from the fuel tank combines with oxygen (O2) from the air at the fuel cell's catalyst surface. The electrochemical reaction is: 2 H2 + O2 -> 2 H2O + electricity. The only chemical product leaving the exhaust is water (released as vapour due to operating temperature). This zero-emission profile is the main environmental selling point of FCEVs over internal combustion engines. Distractors fail: (A) Hydrogen peroxide is not formed under normal fuel cell operation. (B) Hydronium (H3O+) is a transient species in the electrolyte membrane, not exhaust. (C) Oxygen is consumed, not emitted.

Which one of the following has been constituted under the Environment (Protection) Act, 1986?

  1. Central Water Commission
  2. Central Ground Water Board
  3. Central Ground Water Authority
  4. National Water Development Agency
Show answer and solution

Correct answer: C. Central Ground Water Authority

Answer: C. The CENTRAL GROUND WATER AUTHORITY (CGWA) has been constituted under the Environment (Protection) Act, 1986. CGWA was constituted in 1997 under SECTION 3(3) of the ENVIRONMENT (PROTECTION) ACT, 1986 by the Government of India to regulate and control development and management of groundwater resources in the country. CGWA's powers include: - Notifying areas where groundwater use needs to be regulated. - Issuing directions for closure of bore wells in over-exploited areas. - Levying environmental compensation. - Registering existing groundwater users. Distractors: (A) CENTRAL WATER COMMISSION (CWC) is the premier technical organisation for water resources but was set up by executive resolution in 1945, NOT under the EP Act. It is attached to Ministry of Jal Shakti. (B) CENTRAL GROUND WATER BOARD (CGWB) is a subordinate office of the Ministry of Jal Shakti, established in 1970 by reorganisation. CGWB conducts groundwater surveys and provides scientific assessments. It was NOT constituted under the EP Act it is a technical body, not a regulatory authority. (D) NATIONAL WATER DEVELOPMENT AGENCY (NWDA) is a society under Ministry of Jal Shakti (1982) for inter-basin transfer studies. Not under EP Act. Only CGWA, with regulatory powers, draws its statutory authority from the Environment Protection Act 1986. Source: Environment (Protection) Act 1986, Section 3(3) Notification 1997 / Jal Shakti Annual Report.
