Solution

During the electrolysis of aqueous Sodium formate( $H C O O N a$ ) Hydrogen gas and Carbon dioxide gas are obtained.
The Hydrogen gas is produced in the Cathode.
And the Carbon dioxide gas is produced in the Anode.
The cathodic and anodic reaction is,
Anode; $2 H C O O^{-} \to \underset{C a r b o n d i o x i d e g a s}{2 C O_{2} (g)} + 2 e^{-}$
Cathode; $2 H^{+} + 2 e^{-} \to \underset{H y d r o g e n g a s}{H_{2} (g)}$
So the Hydrogen gas is produced in the Cathode.
