Give True $(T)$ or False $(F)$ :
$1.$ $H_2$ is used as fuel in fuel cell.
$2.$ Thermal plants are more pollutants as compared to fuel cell.
$3.$ Fuel cell is pollution free.

(T, T, T) $1.$ $T$: $H_2$ is the most common fuel used in hydrogen-oxygen fuel cells.
$2.$ $T$: Thermal power plants burn fossil fuels,releasing greenhouse gases and pollutants,whereas fuel cells produce electricity through electrochemical reactions with minimal emissions.
$3.$ $T$: Fuel cells are considered pollution-free because the only byproduct of a hydrogen-oxygen fuel cell is water $(H_2O)$.
