CPC H01M 50/269 (2021.01) [B60L 50/70 (2019.02); G05D 3/127 (2013.01); B60L 58/30 (2019.02); B60L 2200/10 (2013.01); H01M 2250/20 (2013.01)] | 4 Claims |
1. An air vehicle,
wherein the air vehicle comprises two or more fuel cells;
wherein each fuel cell comprises an anode outlet manifold;
wherein each fuel cell is disposed in the air vehicle so that water discharge directions of the anode outlet manifolds are different from each other;
wherein the air vehicle further comprises a fuel cell system;
wherein the fuel cell system comprises:
the two or more fuel cells,
a fuel gas system for supplying fuel gas to each fuel cell,
an angle sensor for measuring an inclined angle of each fuel cell,
a gravity acceleration sensor for measuring a gravity acceleration applied to each fuel cell,
an output sensor for measuring an output of each fuel cell, and
a controller;
wherein the fuel gas system comprises a fuel gas supplier;
wherein the controller makes at least one determination selected from the group consisting of a determination as to whether or not the inclined angle of each fuel cell measured by the angle sensor, is equal to or more than a predetermined angle, a determination as to whether or not the gravity acceleration applied to each fuel cell measured by the gravity acceleration sensor, is equal to or more than a predetermined gravity acceleration, and a determination as to whether or not the output of each fuel cell measured by the output sensor, is less than a predetermined output; and
wherein, when the controller determines that any one of the following conditions is satisfied, the controller increases a fuel gas supply from the fuel gas supplier to each fuel cell satisfying the condition: a condition that the inclined angle of each fuel cell is equal to or more than the predetermined angle, a condition that the gravity acceleration applied to the or each fuel cell is equal to or more than the predetermined gravity acceleration, and a condition that the output of each fuel cell is less than the predetermined output.
