Chapter 4. Electricity generation from glucose microbial fuel cell
PublicationThe microbial fuel cell was constructed to generate electricity with simultaneous digestion of a glucose fuel by a bacterial biofilm. The decomposition of glucose resulted in releasing of electrons to an anode and to production of some by-products, e.g. metane or organic acids. It was found that maximum electric power density strongly depended on the proton transport through the proton exchange membrane seperating the anolyte and...

MPPT control - a way to the maximization of energy amount obtained from the PV module
PublicationW układzie MPPT (Maximum Power Point Tracking) poziom mocy maksymalnej jest dynamicznie śledzony dla różnych poziomów napromieniowania i temperatur przy użyciu pamięci, zaprojektowanej jako sterowany mikroprocesorem moduł. Zastosowany algorytm w sposób ciągły poszukuje maksymalnej wartości mocy podawanej ze źródła (modułów PV) oraz pobieranej przez obciążenie. Napięcie wyjściowe z układu MPPT zależy od aktualnych warunków, w jakich...

Global energy transition: From the main determinants to economic challenges regions
PublicationDynamic global energy transition has been accelerating for the last decade. Interestingly, the energy transition is multidimensional and concerns both the dimensions of technique/ technology and the economic, social, institu-tional, and legal spheres (Shuguang et al., 2022; Tzeremes et al., 2022; Ram-zan et al., 2022; Tzeremes et al., 2022). The literature also points to the signif-icant impact of the digitization of the global...
