“…Behind linear adjustment of the polarization curves, the internal resistances of the first, second and third type microbial fuel cell are calculated as 11559 Ω, 29459 Ω, and 26260 Ω, respectively. The internal resistance of a microbial fuel cell consists of three factors, namely, ohmic, activation and diffusion (concentration) resistances . Ohmic resistance is determined on the basis of electrolyte type, electrode properties and membrane factors.…”

“…Diffusion (concentration) resistance by the diffusion rate of reaction products is transferred to the electrode surface and electrolyte . In order to reduce the diffusion resistance, the inert biomass accumulation in the electrodes must be decreased with the high‐performance transfer of the electrons to the anode electrode, protons and oxygen to the cathode electrode.…”

In this study, biofuel properties of poplar wood materials rich in organic materials were investigated for microbial fuel cells. Therefore, in this study, investigates the chemical, biochemical properties with electrochemical performance of single chamber microbial fuel cell manufactured using poplar biomass materials, natural soil, graphite anode electrode and graphite cathode electrode. With the increase in the weight of the poplar tree in the microbial fuel cells, the power density increased. SEM, EDS, FTIR analyses showed that bacillus and coccus type bacteria in the natural structure of the soil act as the catalyst in the anode electrode. Poplar wood, electrodes and bacteria have served in harmony. According to experimental results, the maximum power reaches to 16.88 mW and microbial fuel cell successfully displays a maximum power density of 8555 mW/m 2 . All these results indicate that poplar wood may be appropriate biofuel sources for electrical energy generation as an effective environmentally microbial fuel cell technology.

“…However, the internal resistance of the fuel cell is higher than that of a lithium battery, and the output voltage changes obviously with the fluctuation of load current. For example, the output voltage drops to around half of the open-circuit voltage when the fuel cell works at the maximum output power [ 37 ]. The high-efficiency power converting and management is important for the fuel efficiency.…”

Although the hybrid power system that combines a photovoltaic cell and a lithium-ion battery is increasingly mature and practical, long-lifetime auxiliary power will be still needed in severe weather conditions. A small-volume hydrogen–oxygen fuel cell system based on the hydrolysis of NaBH4 is designed. The fuel cell system contains a tiny hydrogen generator, a hydrogen cleaner, and a small fuel cell stack consisting of three units in series. The relationship between the amount of catalyst and output performance is discussed. The long-time discharging results indicate that the fuel cell system has high power capacity. The compact design allows the fuel cell system to integrate the structure with a photovoltaic cell and lithium-ion cell and forms a hybrid power system with a small package. The power management circuit for these power sources without logic devices is designed and tested. The control strategy selects the photovoltaic–battery subsystem as the primary power source, and the fuel cell subsystem works as the backup power source to handle the circumstance when the energy stored in the battery is exhausted. The test results show that the power management system could switch the power supply automatically and timely under various emergency conditions, and the output voltage remains stable all the time.
