Depends on what you mean by "stuck on a mountain"
The busier tourist areas up in the mountains such as Schilthorn and Jungfraujoch certainly take plastic. As do the feeder regions: Kleine Scheidegg, Mürren, Wengen, Grindelwald, etc.
If you are planning to do some high mountain hiking and ending up at huts/berghauses/etc there will be no plastic possible there.
If you could let us know where you are planning on going we can be more precise.
