1. A system for supplying compressed air to a fuel cell of a vehicle the system comprising:
a first compressor having an inlet for receiving air and an outlet for delivering compressed air to the fuel cell;
an air storage tank arranged upstream and in series with the first compressor, and configured to store compressed air of high pressure; and
an air selection control assembly comprising a selection valve and a switch actuator configured to operate the selection valve;
wherein the selection valve is arranged in between the air storage tank and the inlet of the first compressor, and further in fluid communication with an inlet conduit for receiving fresh air;
wherein the switch actuator is configured to operate the selection valve to selectively control a flow of air to the first compressor such that air can be supplied from the air storage tank to the first compressor or from the fresh air inlet conduit to the first compressor; and
wherein the air selection control assembly is controllable to control the flow of air in response to a determined air characteristic level being any one of an ambient pressure level and an air quality level, such that a supply of air to the first compressor is provided from the air storage tank if the determined air characteristic level is below a threshold value.
