The fuel cells normally circulate hydrogen and oxygen in a closed loop to avoid losses, however they have to be periodically purged (reaction products vented into space) to avoid their effectivity to decrease by contamination. | The fuel cells normally circulate hydrogen and oxygen in a closed loop to avoid losses, however they have to be periodically purged (reaction products vented into space) to avoid their effectivity to decrease by contamination. | ||
As of June 2015, the power generation as well as the coarse power balance of the orbiter is modeled (i.e. switching components on which use electricity will have to be supplied by the running FCs), however not all the details of the electrical distribution system or the reactant feed lines are done. | As of June 2015, the power generation as well as the coarse power balance of the orbiter is modeled (i.e. switching components on which use electricity will have to be supplied by the running FCs), however not all the details of the electrical distribution system or the reactant feed lines are done. In normal operation, the electrical power system should require very little crew intervention. | ||
