BENEFITNishimura’s separators will accelerate
your development of hydrogen fuel cells.

• 

  The quality of a fuel cell is determined by its separator/bipolar plate.

  Amid intensifying competition, what are the issues for fuel cell development?

  As demand for fuel cells expands in step with the focus on carbon neutrality, manufacturers are competing intensively to develop new products. Major automobile manufacturers are stepping up their FCV development, and numerous startups are moving into the market as well. Fuel cells are also being used for an expanding range of applications other than FCV. In this business environment, manufacturers increasingly need to leverage their technology to secure a competitive advantage.

  Separator/bipolar plate quality should be the first priority.

  To improve fuel cell performance, it is necessary to enhance the precision of the separator/bipolar plate, which creates a pathway for supplying hydrogen and air into the generator section of the cell. However, forming complex patterns of minute grooves on thin stainless steel or titanium plates requires an outstandingly high-precision pressing process, and it is extremely difficult to pull off.

  Fuel cell development requires years of experience.

  You need a development partner with profound knowledge and technological expertise.

  The fuel cell market is relatively new, and there are few companies in the world that possess the necessary expertise. As such, you need to carefully select a dependable development partner. In recent years, many fuel cell manufacturers have turned to the Japanese separator/bipolar plate manufacturer Nishimura.

  Nishimura boasts 20 years of experience and knows fuel cells inside out.

  With two decades of experience as a separator manufacturer, Nishimura has comprehensive knowledge about fuel cells and is widely known for its work with leading international OEMs. Nishimura gained a reputation for high-precision metal molding and pressing technology and its ability to manufacture separators from titanium, which is an especially difficult metal to process. Nishimura can also draw on its extensive experience to offer a variety of practical solutions.

  Also a leader in the development of hydrogen electrolyzers

  Electrolyzer development requires international competitiveness.

  In addition to their use as power sources for FCVs, fuel cells are also in demand for other applications. The global rise in clean energy demand is driving demand for industrial applications such as hydrogen power generation and back-up power for large facilities. As a result, hydrogen production has become an urgent priority, leading many companies around the world to focus on electrolyzer development.

  Yet another Nishimura advantage – hydrogen electrolyzer development technology

  Because electrolyzers operate continuously over long periods, their performance is determined by the quality of the separators. Nishimura uses technology developed for fuel cells to enhance its PEM electrolyzers. That is why many manufacturers are turning to Nishimura as their electrolyzer development partner.

It is manufacturing that will also create the future. About NISHIMURA Co., Ltd.
