Dynamic Modelling for Control of Fuel Cells
نویسندگان
چکیده
Fuel-cell dynamics have been investigated with a variable-resistance board applied to a high temperature polymer fuel cell, and a particular pattern has been identified in the voltage-current density diagram. A model has been developed, using a characteristic equation to represent the external circuit as a generally nonlinear resistive load, possibly nonlinear and time-varying, rather than assuming the current density to be an independent variable. The model successfully explains the shape of the transient paths, including the different time constants observed when reversing a transient.

متن کاملLinear Modelling of Marine Vessels Fuel Consumption for Ration of Subsidized Fuel
An approach to deal with the phenomenon of maritime fuel smuggling is to control the quantity of fuel that is supplied to vessels. For the same reason, fuel is delivered to marine vessels in Iran in accordance with the ration defined by the National Iranian Oil Products Distribution Company (NIOPDC). The ration is determined by a fuel consumption formula defined by the Food and Agriculture Orga...
