In the light of emergence of cellular computing, new cellular computing systems based on yet-unknown methods of fabrication need to address the problem of fault tolerance in a way which is not tightly connected to used technology. This may not be possible with existing elaborate fault-tolerant cellular systems so we strive to reach simple solutions. This paper presents a possible solution for increasing fault-tolerance in cellular automata in a form of static module redundancy. Further, a set of experiments evaluating this solution is described, using triple and quintuple module redundancy in the automata with the presence of defects. The results show that the concept works for low intensity of defects for most of our selected benchmarks, however the ability to cope with errors can not be intuitively deduced as indicated on the example of the majority problem.
