    Abstract

    The objective of this study is to design the application system of 1 kW PEMFC to support the ECO-House Solar Hydrogen Energy System. Fuel cell is an electrochemical reactor to convert the chemical energy (H2) as fuel substance, with oxygen (02), to yield water, electrical energy, and heat as a by-product. The system planning of the fuel cell application, is to design the fuel cell operational supporting unit network, i.e.: The air supply unit as oxygen source, in this case the ambient air in Malaysia possess the humidity sufficient for operating the fuel cell, and thus the air only be filtered, pressed by a compressor/blower, and is received in feed tank to keep the stream continuity. The hydrogen unit as fuel substance, uses the hydrogen produced from water electrolysis with 99.9% purity, has been kept in a tank with 150-200 bar pressure, so as before feeding a pressure reduction is undertaken using the pressure regulator valve and is humidified in a cooling water tank, while the unreacted hydrogen is to be recycled and to be fed together with a fresh feeding. The cooling unit employs deionized water in order to utilize for hydrogen humidification, and the water from the tank is pumped to cool the fuel cell stack- while the used water is then cooling in the radiator, and moreover to be incorporated in the tank. The water stream is to be advantaged for the unreacted hydrogen circulation with the jet ejector. The evaluation results has been conducted using the MATLAB software and the electric efficiency found to be 26.46 to the power of fresh hydrogen. When the radiator cooling is carried out without fan (natural convection) with a contact surface enlarged, thus the electric efficiency becomes increased to 27.69 %
