摘要 |
The invention relates to a fuel for using in fuel cells, said fuel being in a solid form and consisting fully or partially of the polymerisation products of the formaldehyde described partly as paraformaldehyde and partly as polyoxymethylene. Especially the anhydrous high-molecular polymerisation products of the formaldehyde, the polyoxymethylenes, and the hydrous polyoxymethylene hydrates are suitable as fuel for using in electrochemical energy converters. |
