Cell Technology Development

During the electrolysis of NaCl brine, chlorine is generated at the anode and sodium hydroxide is produced at the cathode.

The first diaphragm cell developed in Great Britain was the Hargreaves-Bird cell, operated in 1890 by the United Alkali Company. Each cell consisted of a rectangular iron box lined with cement. The box was 10 ft long, 4—5 ft deep, and 2 ft wide, divided into

Twelve cells were mn in series at 2 kA, which corresponds to a current density of 200 A/m, at 4 to 4.5 V, when 60% of the salt is converted to sodium carbonate.

Alkaline fuel cells (AFCs) were one of the first fuel cell technologies developed, and they were the first type widely used in the US space program to produce electrical energy and water onboard spacecraft. These fuel cells use a solution of potassium hydroxide in water as the electrolyte and can use a variety of non-precious metals as a catalyst at the anode and cathode. High-temperature AFCs operate at temperatures between 100°C and 250°C. However, more-recent AFC designs operate at lower temperatures of roughly 23°C to 70°C. 

One of the European and world leaders in hydrogen and fuel cell technology development and implementation worldwide. 

Japan has been an early leader in hydrogen and fuel cell technology development. Since the early 1980s, Japan has invested in research and development into various fuel cell technologies, beginning with PAFCs and MCFCs. Research and development of PEFCs was launched in 1992, and is the focus of Japan s fuel cell research program. The investment to date has amounted to some 97 billion.

EIS has played an important role in fuel cell technology development, as one of the most important research tools for fuel cell diagnosis. EIS can help to identify the contributions from different components or processes to the total impedance of a PEM fuel cell. Such information is very helpful for understanding the fundamental processes within the fuel cell, the performance-structure relationships, and the contributions of various components to performance loss, as well as the associated failure modes and mechanisms EIS thus assists with fuel cell design optimization and selection of the most appropriate fuel cell operating conditions. In this chapter, we will present some typical examples of the applications of EIS in PEM fuel cell research, and an overview of EIS spectra analysis. 

For fuel-cell technology development, it has been important to understand the characteristics and operation of highly dispersed platinum and platinum alloy electrocatalysts. A series of papers on platinum crystallite size determinations in acid environments for oxygen reduction and hydrogen oxidation was published together by Bert, Stonehart, Kinoshita and co-workers.5 The conclusion from these studies was that the specific activity for oxygen reduction on the platinum surface was independent of the size of the platinum crystallite and that there were no crystallite size effects.
