9.5 Conclusion
Nanomaterials are extensively involved in the fabrication and funtioning of nanomaterials. The fuel cells utillized nanomembranes, nanomaterial-based electrodes, and
the nanocatalysts. The nanomaterials are reducing the size of the fuel cells and and
improving their efficency day by day. Most of the naomaterials that are involved in
fuel cells are based on nobel metals. The need of the hour is to develop the ecnomical alternatives of the nanomaterials that are involved in fuel cells, as many of the
nanomaterials are based on nobel metals. The reduction in the cost and improvement
in efficency of the fuel cells is absolute requirement for the hydrogen evolution.
