“…1,2) This closed-type fuel cell, which does not require hydrogen gas to be supplied from outside, is promising as a compact electric power-generating system that would help to satisfy the growing demand for zero CO 2 -emitting energy sources. The rate of hydrogen transport to the fuel cell is one of the most important ratedeterminant processes in the closed-type fuel cell.…”

Thermal Desorption of Hydrogen at the Titanium Hydride-Oxide Interface

Changes in hydrogen distribution in -phase titanium hydrides (TiH 1:92$1:95 ), covered with titanium oxide layers (TiO and TiO 2 ), were investigated by elastic recoil detection analysis (ERDA) after isochronal and isothermal annealing experiments. The hydrogen concentration near to the surface of the hydride exponentially decreased as a function of annealing time in the temperature range from 423 to 523 K. The result shows that the thermal desorption of hydrogen from the hydride is governed by first-order reaction kinetics and greatly depends on the thermal detrapping process. The thermal detrapping rates of hydrogen at the hydride-oxide interface were estimated and their activation energy was determined to be 1:3 AE 0:2 eV.

“…Meanwhile, it overcomes the unneglectable difficulties during hydrogen production, distribution and storage. [8,13,14] Compared with the Metal/O 2 battery such as Zn/O 2 or Fe/O 2 battery, the innovative MH/air system deems to exhibit a relatively long lifetime and high charging efficiency because of the excellent electrochemical property of hydrogen storage alloys. [4,15] Another innovative feature of the MH/air system is that it permits a new battery can be regenerated in two different ways, namely, by gas-solid hydrogenation charging and by electrochemical charging.…”

Abstract.A solid polymer electrolyte metal hydride (MH)/oxygen cell using La 0.78 Ce 0.22 Ni 3.73 Mn 0.30 Al 0.17 Fe 0.50 Co 0.30 in the anode and Nafion as electrolyte is described and investigated experimentally. In this work, the discharge performances of the cell are compared in two charging ways, namely, electrochemical and gas-solid hydrogenation. The specific discharge capacityby gas-solid hydrogenation method is about 59.3mAh·g -1 , while almost few specific discharge capacityis obtained by electrochemical method in this work. The cell is characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. And the ex-situ XRD results of the cell charged by gas-solid hydrogenation method show that an electrochemical reaction between hydrogen and oxygen does happen, and little observable side reaction occurs. Moreover, the stability of the MH electrode depending on various relative humidity is investigated. The results indicate that solid-state MH/O 2 cell using Nafion as electrolyte is technically feasible, while the control of the water content during charge/discharge processes and the catalyst loading must be the key points. More than that, further researches are still required to enhance both charge/discharge capacity and reversibility.

“…In the charging process, the proton battery can decompose water with the assistance of power supply to generate hydrogen ions, which are stored in the porous carbon-based material as a hydrogen storage electrode. Folonari and Condon et al [ 2 , 3 ] thought that the new kind of fuel cell composed of hydride electrode and solid electrolyte had higher energy density and a more compact simple structure, and, if it maintained the advantages of a traditional fuel cell, this structure could enhance the reliability and performance of electric vehicles significantly. At present, the mainstream fuel cells mostly store the hydrogen in the hydrogen storage tank and the hydrogen storage tank is installed on the carrier (e.g., automobile and generator).…”

The proton battery possesses water electrolysis, proton storage and discharging functions simultaneously, and it can be manufactured without expensive metals. Use the principle of proton exchange membrane water electrolysis for charging, store it in the activated carbon on the hydrogen side and use the principle of proton exchange membrane fuel cell for discharge when needed. According to the latest literature, it is difficult to obtain the exact important physical parameters inside the proton battery (e.g., voltage, current, temperature, humidity and flow), and the important physical parameters are correlated with each other, which have critical influence on the performance, lifetime and health status of the proton battery. At present, the condition of the proton battery is judged indirectly only by external measurement, the actual situation inside the proton battery cannot be obtained accurately and instantly. Therefore, this study uses micro-electro-mechanical systems (MEMS) technology to develop a flexible 5-in-1 microsensor, which is embedded in the proton battery to obtain five important physical parameters instantly, so that the condition inside the proton battery can be mastered more precisely, so as to prolong the battery life and enhance the proton battery performance.
