fuel with battery power.

Checking the Gas
Production
Now electrolysis begins in the
fuel cell, which is the splitting
of water into its elements, hy-
drogen and oxygen. The water
that remains in the tubes is
pushed from the cell through
the long hoses to the gas
tanks and the water tank by
the gas that is produced. The
larger tank fills with hydrogen
gas, the smaller one with oxy-
gen. After just a few minutes,
you will be able to see how the
gases push the water down in
their storage tanks and the
water level in the water tank
starts to rise.
When the first bubbles rise
out of the gas tanks to the
water’s surface, the tanks are
full.
Remove the cables between
the fuel cell and solar panel.
