Challenge

Improving the efficiency and life of a fuel cell Understanding the complex flow inside the tiny individual cells

Story

Fuel cells represent one of the most important automotive design challenges of the 21st century because of their potential to eliminate dependence on fossil fuel sources and to eliminate carbon emissions that are theorized to be responsible for global warming. Yet fuel cells provide enormous design challenges, primarily increasing their power and robustness while reducing their cost to levels that will make them competitive with internal combustion engines. Flow simulation is playing a major role in this process by enabling engineers to understand and visualize the complex flow within with the fuel cell which plays a critical role in its performance.

Benefits

Increase power generation efficiency Increase in life of cell Engineering time savings
