Within the next decade, hydrogen fuel cell technology may emerge
as a popular engine alternative within the automotive industry.
Hydrogen gas storage technology, which remains a key issue to
public safety, is continuing to advance. However, recent research
has shown that polymer tanks that are reinforced with carbon fiber
can achieve operating pressures above 50 MPa. For this example,
consider a hydrogen refueling station that (for safety reasons)
dispenses hydrogen gas to vehicles at a constant 20 MPa. Your car...

Hydrogen gas is used as a fuel instead of fossil fuels. Storage
of hydrogen is a challenge. One avenue of research involves
chemical storage such as incorporating hydrogen as part of a metal
hydride. In the following reaction sodium borohydride, NaBH4, is
used as a means for storing and later generating the hydrogen gas
in situ where it is needed as a fuel. Application of heat and use
of a catalyst drives the reaction forward. NaBH4(s) + 2 H2O(l) →...

In a hydrogen-oxygen fuel cell, gaseous hydrogen serves as the
fuel, oxygen in the air as the oxidizer, and the reaction product
is water. Consider that flat plates of Pt are used as electrodes at
25°C and fuel and air are supplied at 1 atm. [20%] (a) Write the
Nernst expression for each half-cell reaction. (b) What is the
overall cell reaction? (c) Calculate the cell voltage, Ecell, given
the above conditions. (d) Suppose that the supply of hydrogen and...
