“…The hydrogen flow are using continuous mode, but it supplied based on request load. The reactant control system build [34] are used to ensure the gases entering the stack is sufficient with the amount of power produced. Otherwise for oxygen in cathode sides, fans are used to blow source of oxygen from the air.…”

This paper presented the transformation of a golf cart system powered lead acid battery into an environmental friendly hybrid vehicle. The design developed by using an advantage contributes by the uprising alternative power source candidate which is Proton Exchange Membrane Fuel Cell (PEMFC) and the maintenance free energy storage device, a supercapacitor (SC). The fuel cell (FC) stack was an in house manufactured with 450 W (36 V, 12.5 A) power, while the SC was from Maxwell Technologies (48 V, 165 F). This two power sources were controlled by the mechanical relay, meanwhile the reactant (hydrogen) are control by mass flow controller (MFC) both signaled by a National Instrument (NI) devices. The power management controller are programmed in the LabVIEW environment and then downloaded to the NI devices. The experimental result of the power trend was compared before and after the transformation with the same route to validate the effectiveness of the proposed power management strategy. The power management successfully controls the power sharing between power sources and satisfies the load transient. While the reactant control managed to vary the hydrogen mass flow rate feed according to the load demand in vehicular applications.

“…In this case, the outcomes were gathered experimentally where capabilities of dynamic response control were achieved. Despite in real-time applications, the direct manipulation of gases for PEMFC can increase the risk of accidents because of the sensitivity of H 2 [13]. Additionally, accurate models of PEMFC are mainly non-linear due to the dependence on partial reactancts pressures and temperature [14].…”

Proton exchange membrane fuel cells (PEMFC) are capable of transforming chemical energy into electrical energy with zero emissions. Therefore, these devices had been a point of attention for the scientific community as to provide another solution to renewable sources of energy. Since the PEMFC is commonly driven with a power converter, a controller has to be implemented to supply a convenient voltage. This is an important task as it allows the system to be driven at an operative point, which can be related to the maximum power or an user desired spot. Along this research article, a robust controller was compared against a fuzzy logic strategy (with symmetric membership functions) where both were implemented to a commercial PEMFC through a dSPACE 1102 control board. Both proposals were analysed in an experimental test bench. Outcomes showed the advantages and disadvantages of each scheme in chattering reduction, accuracy, and convergence speed.

“…Usually this happen when the fuel is supplied at a fixed and high stoichiometric ratio in orders to maintain the desired current density [8,9]. But if the stoichiometric ratio is too low, will result in low performance [10,11]. But problems often arise when the imposed loading varies and the supplied reactants are insufficient to produce the needed power.…”

Efficient operation results from a proper control strategy. In the operation and performance of a Proton Exchange Membrane Fuel Cell (PEMFC), the hydrogen gas flow rate is one of the most essential control parameter in addition to operating pressure, water management, temperature and humidity. This is because of the high cost and amount of energy are required to produce the purity hydrogen gas. In this paper, a Proportional Integral Derivative (PID) feedback control system is used to control the hydrogen flow rate. A strategy is adapted to balance the hydrogen use based on the loading requirements, especially during startups and sudden power demands. This system is implemented using National Instrument (NI) devices powered by the LabVIEW program. This is due to its simplicity and customization flexibility for measuring, processing and recording data. Designed structure allows the real-time implementation of a robust control law that is able to address the related nonlinearities and uncertainties without incurring a heavy computational load for the controller algorithm. While it facilitating a fast sampling rate according to the needs of the power system. Test results from the controller show that the new fuel control system provides good performance by reducing the amount of wasted hydrogen gas compared with that of the previous open loop system by 30 % to over 80 % saved by the varied load. This improvement is beneficial for any PEMFC that experiences fluctuating power demand, especially for vehicle applications.Keywords: PEM fuel cell, proportional integral derivative, reactant controller, LabVIEW, national instrument Abstrak Operasi yang cekap terhasil dari strategi kawalan yang baik. Dalam operasi dan prestasi Fuel Cell Membran Penukaran Proton (PEMFC), kadar aliran gas hidrogen adalah salah satu parameter kawalan yang paling penting selain dari tekanan operasi, pengurusan air, suhu dan kelembapan. Ini kerana kos yang tinggi dan jumlah tenaga dikehendaki untuk menghasilkan gas hidrogen berketulenan tinggi. Dalam kertas kerja ini, sistem kawalan Perkadaran, Kamiran dan Perbezaan (PID) suap balik digunakan untuk mengawal kadar aliran hidrogen. Strategi disesuaikan untuk mengimbangi penggunaan hidrogen berdasarkan keperluan bebanan, terutamanya pada permulaan dan permintaan kuasa secara tiba-tiba. Sistem ini dilaksanakan dengan menggunakan peranti instrumen nasional (NI) yang dikuasakan oleh program LabVIEW. Ini kerana ia ringkas dan fleksibel untuk mengukur, pemprosesan dan rakaman data. Struktur yang direka bentuk membolehkan pelaksanaan masa sebenar hukum kawalan yang mantap yang mampu menangani keadaan yang tidak linear dan tidak menentu tanpa memerlukan pengiraan yang sukar untuk algoritma pengawal. Sambil itu, ia memudahkan kadar pensampelan yang cepat mengikut keperluan sistem kuasa. Hasil ujian dari pengawal menunjukkan bahawa sistem kawalan sel fuel yang baru memberikan prestasi yang baik dengan ISSN -2506 Ros Emilia et al: STUDY OF HYDROGEN CONSUMPTION BY CONTROL SYSTEM IN PROTON EXCHANGE MEMB...
