Abstract: Embodiments of the present invention provide improved space utilization concepts for aircraft, and particularly to using under floor space created by the envelope designed to house an airstair system. For example, this space may be used to house and integrate one or more fuel cell system(s) and/or components, such as hydrogen tanks and/or the fuel cell body, such that the fuel cell system can deliver useful byproducts to support various aircraft functions. Additionally or alternatively, the space may be used to store other components.
