“…On the other hand, Figures and show the FC and HV system efficiencies, ƞ FCS and ƞ HV , calculated from the following expressions :

η_{FCS} = \frac{\int_{italiccycle} P_{F C T} d t}{N_{italicfc} \cdot \int_{italiccycle} P_{H 2} d t}

η_{HV} = \frac{\int_{italiccycle} P_{italicload} d t}{N_{fc} \cdot \int_{italiccycle} P_{H 2} d t + \int_{italiccycle} P_{italicbat} d t}

where P FCT is the output net power supplied by the two FCs, N fc is the number of FCS connected in parallel, P H2 is the incoming hydrogen power in an FC, calculated by Equation (), and P load is the traction power of the HV.…”

This article presents a comparative study among four control strategies for the energy management of a fuel cell (FC) battery-powered hybrid system applied to a surface tramway of 400 kW, which, at present, operates as catenary-powered tramway in the center of Seville, Spain. The proposed hybrid system is composed of a polymer electrolyte membrane FC with a unidirectional dc/dc boost converter and a rechargeable nickel-metal hydride battery with a bidirectional dc/dc converter, both of which are coupled to a traction dc bus. This configuration allows a suitable control of the energy of the hybrid tramway and the traction dc bus voltage.The polymer electrolyte membrane FC and nickel-metal hydride battery models are designed from commercially available components. The control strategies presented in this work are as follows: (i) control strategy based on operating states of the tramway (state machine control), (ii) control strategy based on cascade control loops (cascade control), (iii) control strategy based on fuzzy logic (fuzzy logic control), and (iv) control strategy based on the fuel consumption minimization (equivalent consumption minimization strategy. The control strategies are tested and compared for the real driving cycle of the tramway. The simulation results reflect the optimal performance of the presented control systems.The hybrid system is composed of the following elements: (i) PEM FC, (ii) Ni-MH battery, (iii) dc/dc unidirectional converter (FC converter), (iv) dc/dc bidirectional converter (battery converter), (v) tramway loads, which include traction system and auxiliary services, (vi) braking chopper, and (vii) energy

Dynamics of proton exchange membrane fuel cells (PEMFC) with hydrogen storage system for generating part of Hercules airplanes electrical energy is presented. Feasibility of using fuel cell (FC) for this airplane is evaluated by means of simulations. Temperature change and dual layer capacity effect are considered in all simulations. Using a three-level 3-phase inverter, FC's output voltage is connected to the essential bus of the airplane. Moreover, it is possible to connect FC's output voltage to airplane DC bus alternatively. PID controller is presented to control flow of hydrogen and oxygen to FC and improve transient and steady state responses of the output voltage to load disturbances. FC's output voltage is regulated via an ultracapacitor. Simulations are carried out via MATLAB/SIMULINK and results show that the load tracking and output voltage regulation are acceptable. The proposed system utilizes an electrolyser to generate hydrogen and a tank for storage. Therefore, there is no need for batteries. Moreover, the generated oxygen could be used in other applications in airplane.

“…Despite the lead acid battery has a low energy-to-weight ratio and a low energy-to-volume ratio, it has excellent ability to supply high surge currents, which can provide relatively large power-to-weight ratio as a complement of fuel cell characteristics [3]. Hybrid power source system becomes a trend to supply the energy for applications, especially in vehicle applications [11] [15]. Fig.…”
