The present invention provides, in a first aspect, an electrical generation system which includes an electrolyzer and a fuel cell system. The electrolyzer is coupled to a source of water and a power source. The electrolyzer is configured to generate oxygen and hydrogen utilizing water from the water source and electrical power from the power source. The fuel cell system is coupled to the electrolyzer to receive a flow of the hydrogen from the electrolyzer at an anode thereof. The fuel cell system includes a cathode having a cathode chamber coupled to a source of ambient air. The cathode chamber is coupled to the electrolyzer to selectively allow a flow of the oxygen from the electrolyzer to the cathode chamber and to selectively allow a flow of air from the source of ambient air to the cathode chamber. The fuel cell system is configured to generate electricity in a fuel cell reaction utilizing the hydrogen and the oxygen.
