GreenCell Inc., a designer of hydrogen fuel cells, has announced that it has completed development of a new fuel cell stack design that will help improve efficiency of hydrogen energy systems. The stack was designed for the company’s UltraTemp-C models, but could conceivably be utilized in the fuel cells from other companies. GreenCell believes that the new stack design will help cut the costs associated with fuel cells. The design will not have a dramatic impact on the cost of production, but will help make maintenance more cost effective.
The new stack design incorporates flexible seal materials that help reduce the occurrence of hydrogen leakage. Leakage can have significant implications for the performance of fuel cells. If fuel cells do not have enough hydrogen to use, they are not viable energy systems. Maintenance of conventional fuel cells can be somewhat difficult for those without an engineering background. The flexible materials used by GreenCell make the fuel cells more durable.
GreenCell claims that the stack design will also enable fuel cell owners to easily replace individual components, making maintenance less taxing. The stack design is meant for solid oxide fuel cells. These fuel cells are generally more cost effective than conventional models, but operate at higher temperatures. These temperatures put stress on the fuel cell’s internal components, making maintenance a serious issue for those utilizing these fuel cells. GreenCell believes that its new stack design will help alleviate some of the stress associated with fuel cell maintenance.
