Development of Fine Chemical Catalysts

Our company defines "fine chemical catalysts" as follows: "Unlike bulk chemical catalysts which are produced in mass amounts, fine chemical catalysts are high-performance catalysts that are produced in small amounts for special applications with high added value." Our company works daily to produce fine chemical catalysts.

Normally, fine chemical products require an alloying process with numerous stages and generate many waste products. Therefore, in recent years, from the perspective of atom economy, there is demand for shifting and reconstructing to chemical reactions with smaller environmental load.

As a catalyst manufacturer, our company is working to resolve these issues by developing new fine chemical catalysts. Ultimately, we seek to provide our customers with value from highly-efficient, clean, and environmentally-friendly chemical reactions.

Strengths of our company

  • Flexible response to changes in the social environment
  • Strategic partnerships with key players in the industry

Development of catalysts for fuel cells

Catalysts for fuel cells is a new business area in which N.E. CHEMCAT CORPORATION is placing our greatest focus in recent years. Fuel cells are powered by the reaction energy of hydrogen. There are great expectations for fuel cells as a clean next-generation energy source that does not emit CO2. Catalyst technology for accelerating the reaction energy generation of hydrogen is essential for realizing fuel cells.

Our company has already started development for home fuel cells. We have also developed electrode catalysts for fuel cell vehicles. In Japan, there are plans to build at least 100 hydrogen fueling stations dedicated to fuel cell vehicles by 2020. Accordingly, the market is expected to grow.

We will continue to actively develop electrode catalysts for vehicle fuel cells. Our goal is to achieve low cost and high performance.

Our development history of fuel cell electrode catalysts

NECC: Development results for core-shell catalysts

Performance of customer batteries equipped with NECC core-shell catalysts (Pt/Pd/C; 1st generation)

  • Catalyst activation 4 times Pt/C
  • Battery performance 4 times Pt/C
  • Pt usage amount 1/4 of Pt/C
  • PBattery can be configured with ultra-low Pt support amount (for example 0.025mg/cm2)
  • Higher output than PtCo/C in the overall current density region
    *Particularly high performance observed in the high current density region.

Advance of mass-production technology

NECC is steadily improving the performance of core-shell catalysts and advancing mass-production technology.

NECC core-shell catalysts outperform Pt alloy catalysts even when the Pt amount is reduced. This achieves the performance and cost needed for low-end models.
