No one knows?
This is the "metadata" error with some IC2 recipes that I mentioned earlier. When you look at 10K Coolant Cells, then item number is 4354:1 - the ":1" part is called "metadata". In this modpack, most if not all recipes using 10K Coolant Cells calls for Item#4354, not Item#4354:1, so the recipe doesn't work.
What Jason McRay said is to put the 10K Coolant Cell into a Crafting Table all by itself, and there should be a recipe to convert the item this way from Item#4354:1 to Item#4354. However, it did not work for my and I had to ask my server operator to "creative-spawn" the items into the game in exchange for my raw materials.
At the time I was dealing with this issue, I did not know about any Vacuum Freezer recipe, so I did not try that method. But it makes sense, putting coolant cells into a Freezer to make them!! It's just not obvious in NEI because who looks at metadata? I sure don't. The Vacuum Freezer recipe looks like "put a 10K Cell in, get a 10K Cell out", so it looks like it is a broken recipe.... but its the metadata, you have to look closer at that recipe.
You will have to use the "Jason McRay" method (put item into a crafting table by itself) for stuff like "Advanced Heat Exchanger" which is required to make a Nano Suit. But I still had issues with other IC2 items and had to ask for help from the guy who runs my server.
