State fuels supplied to cells will be hydrogen and oxygen

Reference no: EM13661991

General Electric Co. has developed an advanced fuel-cell battery that will provide the primary power needed during orbit by space capsules. The peak load delivered by the battery will be just under 2kW. The facility will be accumulating from ion-exchange-membrane cells, in which the membranes are sheets of a tough, undisclosed plastic.

The fuels supplied to the cells will be hydrogen and oxygen. Though fed in the gaseous state during battery operation, these two elements will be sorted as liquid, to conserve space.

The equipment is inherently reliable for the reason that it is simple, and it achieves 60% thermal efficiency under normal load. As well, the battery will yield a by-product that is highly valuable in space-flight---- a pint of pure drinkable water for each kilowatt-hour of operation.

If the O2 as well as the H2 are stored as saturated liquids at their normal boiling point, explain what is the enthalpy change per g mol of O2 between the liquid storage tank as well as the state of which the O2 enters the fuel cell (1.5atm, 27oC)
