In a typical fuel cell, the reactants (R) and product (P) are:

Options

A. `R = H_(2(g)^(+)), O_(2(g)), P= H_(2)O(l)`
B. `R = H_(2(g)^(+))^(@) , O_(2g^(+)) , P H_(2)O_(l)`
C. `R = H_(2(g)^(+)), N_(2)(g)^(+), P = NH_(3)(aq)`
D. `R= H_(2(g)^(+)) O_(2(g)), P= H_(2)O(2l)`

Answer

A

Explanation

Cell reaction involved in hydrogen oxygen fuel cell is
`2H_(2)(g) + O_(2)(g) to 2H_(2)O(l)`
Thus, `R = H_(2)(g), O_(2)(g), P = H_(2)O(l)`
