Hydrogen filling station design for fuel cell vehicles

Abstract

After the Energy Bill was announced in 2005, a transition of national energy system from hydrocarbon to hydrogen had been envisioned. However, safe and convenient refueling and widespread availability of hydrogen from various energy sources are the prerequisite for the development of hydrogen economy. This paper focuses on the design of a hydrogen filling station with on-site hydrogen production by electrolysis of water. The proposed virtual wind farm and on-site installed photovoltaic (PV) supply the main and renewable energy for electrolyzers in the station. The utility electricity is served as an auxiliary energy resource to compensate the intermittence of wind and solar. Since the market clearing price (MCP) can change dramatically in the deregulated power market, the station can participate in the power market with a hydrogen storage tank. Based on the forecasting of wind power with artificial neural network (ANN) model and MCP with the statistical model, this paper proposes an optimization algorithm for the hydrogen production schedule and the strategy of power trading to optimize the production costs of the station.

Multiresolution PID control of Brushless DC motor in fuel cell electric vehicles

“…Ancillary subsystems include hydrogen delivery, oxidant air supply and cooling air supply. The produced voltage by PEMFC stack depends on temperature inside the cells, inlet flow rate of Hydrogen, inlet flow rate of Oxygen and with load current [6]. Therefore an interleaved boost converter is needed to stabilize and boost stack voltage to the required load level.…”

Electricity-Heat-Hydrogen Modeling of Hydrogen Storage System Considering Off-Design Characteristics

“…It should be noted that as for the fitting problem, the input power and the electrolyte temperature are taken as the independent variables, and the output power is taken as the dependent variables. The results of the fitting coefficients are achieved by minimizing the mean relative error between the real output power and the calculated output power from (6). The mean relative error for the form of ( 6) is 1.46%, which is small enough and acceptable.…”

“…Therefore, the electrochemical characteristics of the fuel cell can be fitted by a quadratic function including a quadratic term of input power with a negative coefficient and a bilinear term between input power and electrolyte temperature. Similar to (6), the electrochemical characteristics of the fuel cell is also formulated in the per-unit form, as shown in (8).…”

“…As for research on the scheduling of the HSS, the simple linear model is widely used, using a linear efficiency constant to describe the relationship between the input power and output power. The simple linear model is used to solve the scheduling strategy for the HSS in the market in [6]. In [7], the simple linear model is also applied to solve the optimal integrated scheduling for the HSS, wind turbines, and nuclear power plants.…”

“…However due to different consumer's Hydrogen consumption patterns, the prices for Hydrogen transport may vary. The market clearing prices (MCP) may change dramatically in open energy market and the stations can participate in Hydrogen fuel trading [100]. DSOs will help in this energy trading.…”
