In August 1940, 1,540,000 [French] prisoners were taken into Germany, where roughly 940,000 remained until 1945, when they were liberated by advancing Allied forces. At least 3,000 Senegalese Tirailleurs were murdered after being taken prisoner. While in German captivity, 24,600 French prisoners died; 71,000 escaped; 220,000 were released by various agreements between the Vichy government and Germany; several hundred thousand were paroled because of disability and/or sickness.

3,000,000 (circa): French Army strength in September 1939 (2,240,000 in France north of the Alps + 150,000 at the Alps + 600,000 Overseas [Source]) (this 3 milion is for autumn 1939; it presumably rises considerably by May 1940)
(May 1940: France is defeated. Hundreds of thousands escape to Britain and elsewhere to continue the war effort under General De Gaulle)
1,540,000: French POWs taken to Germany, May to June 1940
...940,000: French POWs, still interned, liberated circa spring 1945 [61.0% of those interned as POWs in 1940]
...504,400: Released by Germany at some point between 1940 and 1945 [32.8%]
.....71,000: Escaped (not recaptured?) (not specified when) [4.6%]
.....24,600: Died in German POW camps [1.6% death rate of those interned in German camps]
As most French soldiers were apparently not interned at all (some due to evacuation from a collapsing France and some due, presumably, to being considered unimportant by German authorities), perhaps 0.5-0.75% of entire French Army can be said to have died in German POW camps, a figure much lower than that for German POWs after the war.
I should also note that some number of these French POWs who died will have been killed by Allied air raids. Up to one thousand British POWs are said to have been killed by Allied air raids; if so, as there were more French POWs than British, this number may likely be higher for the French.
