“…The analysis of the dynamics of heat flow in thermal structures is important in many areas such as Fuel-Cell based systems, [1], motors, [2], [3], Scanning Thermal Microscopy or Differential Scanning Calorimetry, [4]. In Scanning Thermal Microscopy, for example, nanotopography imaging is achieved by tracking temperature or heat flow changes in large arrays of cantilevers with integrated heater-thermometers kept at constant temperature, [5].…”

Abstract-The objective of this paper is to analyze the dynamics of heat flow in thermal structures working under constant temperature operation. This analysis is made using the tools of sliding mode controllers. The theory is developed considering that the thermal system can be described using diffusive representation. The experimental corroboration has been made with a prototype of a wind sensor for Mars atmosphere being controlled by a thermal sigma-delta modulator.This sensor structure allows to analyze experimentally the timevarying case since changes in wind conditions imply changes in the corresponding thermal models. The diffusive symbols of the experimental structures have been obtained from openloop measurements in which pseudo-random binary sequences of heat are injected in the sensor. With the proposed approach it is possible to predict heat flux transient waveforms in many applications.

“…156 The suggested methods of control are committed for air fed subsystem control, 157,158 temperature control 143 and humidification control. 159 However, there still exists some drawbacks of the first level of control which needs to be dealt with seriously. The issues are as follows: (a) Present studies are focusing on feedback control strategy with a fixed reference value, but the chemical processes yet change with progress in time; (b) As the FC stack involves various different control subsystems, so while designing the control system the interactions between the different subsystems should be considered and (c) The robustness and flexibility of the designed control techniques while precisely modeling a random FC system in the entire life span must be given emphasis in practice.…”

“…Among the proposed control methods, most are dedicated to the air fed subsystem control since the subsystem shows high-nonlinear behavior [65,66]. The temperature and humidification controls have also begun to attract the attention of the control community [64,90]. Some problems on the first level control are still open.…”

Since the last two decades, microgrid, as one typical structure in smart grid framework, has been receiving increasing attention in the world. Meanwhile, fuel cell (FC), as one promising power source, has redrawn the attention of both academia and industry since the beginning of 21th century. Some encouraging achievements in FC technology have been realized thanks to the efforts taken in the last years. Due to this, it is seen that FC, as a clean and efficient energy source, is penetrating into different fields. Among the applications, integrating FCs into microgrids has shown interesting advantages on improving the performance of microgrids and promoting the use of the hydrogen energy. Some ongoing projects have shown that FCs of different power scales can be integrated into microgrids smartly and in different manners. Along with the advantages carried by the combination of the two technologies, many challenges lying on multiple domains are faced in the process. The challenges can be from the FC, the microgrid, and the integration of these two technologies. In this review paper, the advantages of integrating FCs into microgrids are summarized after recalling the knowledge background of FC. The challenges and ongoing researches on FCs and FCs based microgrids are then reviewed. Based on the analysis, the research directions are then extracted in view of the challenges.
