Hydrogen Fuel Cell
What is a hydrogen fuel cell?
- The hydrogen fuel cell uses hydrogen and air to generate electricity, producing only heat and water in the process.
- Hydrogen fuel cells like the one present in the bus produce electricity by combining hydrogen and oxygen atoms.
- The two gases react across an electrochemical cell similar to a conventional battery cell to produce electricity, water and small amounts of heat. This electricity is then used by electric motors to propel the vehicle forward.
- Fuel cells work in a similar manner to conventional batteries found in electric vehicles but they do not run out of charge and don’t need to be recharged with electricity.
- They continue to produce electricity as long as there is a supply of hydrogen.
- Just like conventional cells, a fuel cell consists of an anode (negative electrode) and cathode (positive electrode) sandwiched around an electrolyte.
What are cloudbursts?
- A cloudburst is a localised but intense rainfall activity. Short spells of very heavy rainfall over a small geographical area can cause widespread destruction, especially in hilly regions where this phenomenon is the most common.
- Not all instances of very heavy rainfall, however, are cloudbursts.
- A cloudburst has a very specific definition: Rainfall of 10 cm or more in an hour over a roughly 10 km x 10-km area is classified as a cloudburst event.
- By this definition, 5 cm of rainfall in a half- hour period over the same area would also be categorized as a cloudburst.
