State two advantages of `H_(2)-O_(2)` fuel cell over ordinary cell.

Explanation

**Step-by-Step Solution:**

1. **Definition of Fuel Cell:**
- A fuel cell is a device that generates electrical energy through an electrochemical reaction using fuel (in this case, hydrogen) and an oxidant (oxygen).

2. **Advantage 1 - Continuous Electricity Production:**
- One significant advantage of hydrogen-oxygen fuel cells is their ability to produce electricity continuously as long as the fuel (H₂) and oxidant (O₂) are supplied. This means that they can operate for extended periods without the need for recharging, unlike ordinary cells which have a limited lifespan and require recharging after depletion.
