Thermal behavior of small lithium-ion battery during rapid charge and discharge cycles
TL;DR: In this article, the authors measured the temperature rise of a small lithium-ion secondary battery during rapid charge and discharge cycles and calculated the heat transfer coefficient as a function of cell and ambient temperatures.

An experimental investigation of gaseous flow characteristics in microchannels
TL;DR: In this paper, the authors investigated the frictional characteristics of nitrogen and helium flows in three different micro-channels (hydraulic diameter range 3-10 w m) and observed that the reduced frictional resistance of gaseous flow in a trapezoidal cross-section microchannel was observed to be smaller than that in the conventional-sized channel.

Steam electrolysis performance of intermediate-temperature solid oxide electrolysis cell and efficiency of hydrogen production system at 300 Nm3 h−1
TL;DR: The steam electrolysis performance of an intermediate-temperature solid oxide electrolysis cell (SOEC) was measured at 650°C at various steam concentrations as mentioned in this paper, and the cell voltage decreased with increasing steam concentration, which was attributed to a decrease in the steam electrode polarization.

Separation and compression characteristics of hydrogen by use of proton exchange membrane
TL;DR: In this paper, the authors preliminarily tested the hydrogen separation pump and hydrogen compression pump, and demonstrated their good performance with the use of our simulation model of a hydrogen pump, which was made by modifying our FC simulation model and the test results agreed well with the calculated results.

Cycle analysis of planar SOFC power generation with serial connection of low and high temperature SOFCs
TL;DR: In this article, a power generation system consisting of two-staged solid oxide fuel cells with serial connection of low and high temperature SOFCs was investigated, and the numerical results showed that the power generation efficiency of the two-stage SOFC was 50.3% and the total efficiency of power generation with gas turbine was 56.1% under standard operating conditions.
